+=============================================
+Sound Blaster Audigy mixer / default DSP code
+=============================================
+
+This is based on sb-live-mixer.rst.
+
+The EMU10K2 chips have a DSP part which can be programmed to support
+various ways of sample processing, which is described here.
+(This article does not deal with the overall functionality of the
+EMU10K2 chips. See the manuals section for further details.)
+
+The ALSA driver programs this portion of chip by default code
+(can be altered later) which offers the following functionality:
+
+
+Digital mixer controls
+======================
+
+These controls are built using the DSP instructions. They offer extended
+functionality. Only the default build-in code in the ALSA driver is described
+here. Note that the controls work as attenuators: the maximum value is the
+neutral position leaving the signal unchanged. Note that if the same destination
+is mentioned in multiple controls, the signal is accumulated and can be wrapped
+(set to maximal or minimal value without checking of overflow).
+
+
+Explanation of used abbreviations:
+
+DAC
+ digital to analog converter
+ADC
+ analog to digital converter
+I2S
+ one-way three wire serial bus for digital sound by Philips Semiconductors
+ (this standard is used for connecting standalone DAC and ADC converters)
+LFE
+ low frequency effects (subwoofer signal)
+AC97
+ a chip containing an analog mixer, DAC and ADC converters
+IEC958
+ S/PDIF
+FX-bus
+ the EMU10K2 chip has an effect bus containing 64 accumulators.
+ Each of the synthesizer voices can feed its output to these accumulators
+ and the DSP microcontroller can operate with the resulting sum.
+
+name='PCM Front Playback Volume',index=0
+----------------------------------------
+This control is used to attenuate samples for left and right front PCM FX-bus
+accumulators. ALSA uses accumulators 8 and 9 for left and right front PCM
+samples for 5.1 playback. The result samples are forwarded to the front DAC PCM
+slots of the Philips DAC.
+
+name='PCM Surround Playback Volume',index=0
+-------------------------------------------
+This control is used to attenuate samples for left and right surround PCM FX-bus
+accumulators. ALSA uses accumulators 2 and 3 for left and right surround PCM
+samples for 5.1 playback. The result samples are forwarded to the surround DAC PCM
+slots of the Philips DAC.
+
+name='PCM Center Playback Volume',index=0
+-----------------------------------------
+This control is used to attenuate samples for center PCM FX-bus accumulator.

+Guide to using M-Audio Audiophile USB with ALSA and Jack
+========================================================
+
+v1.5
+
+Thibault Le Meur <Thibault.LeMeur@supelec.fr>
+
+This document is a guide to using the M-Audio Audiophile USB (tm) device with
+ALSA and JACK.
+
+History
+=======
+
+* v1.4 - Thibault Le Meur (2007-07-11)
+
+ - Added Low Endianness nature of 16bits-modes
+ found by Hakan Lennestal <Hakan.Lennestal@brfsodrahamn.se>
+ - Modifying document structure
+
+* v1.5 - Thibault Le Meur (2007-07-12)
+ - Added AC3/DTS passthru info
+
+
+Audiophile USB Specs and correct usage
+======================================
+
+This part is a reminder of important facts about the functions and limitations
+of the device.
+
+The device has 4 audio interfaces, and 2 MIDI ports:
+
+ * Analog Stereo Input (Ai)
+
+ - This port supports 2 pairs of line-level audio inputs (1/4" TS and RCA)
+ - When the 1/4" TS (jack) connectors are connected, the RCA connectors
+ are disabled
+
+ * Analog Stereo Output (Ao)
+ * Digital Stereo Input (Di)
+ * Digital Stereo Output (Do)
+ * Midi In (Mi)
+ * Midi Out (Mo)
+
+The internal DAC/ADC has the following characteristics:
+
+* sample depth of 16 or 24 bits
+* sample rate from 8kHz to 96kHz
+* Two interfaces can't use different sample depths at the same time.
+
+Moreover, the Audiophile USB documentation gives the following Warning:
+ Please exit any audio application running before switching between bit depths
+
+Due to the USB 1.1 bandwidth limitation, a limited number of interfaces can be
+activated at the same time depending on the audio mode selected:
+
+ * 16-bit/48kHz ==> 4 channels in + 4 channels out
+
+ - Ai+Ao+Di+Do
+
+ * 24-bit/48kHz ==> 4 channels in + 2 channels out,
+ or 2 channels in + 4 channels out
+
+ - Ai+Ao+Do or Ai+Di+Ao or Ai+Di+Do or Di+Ao+Do
+
+ * 24-bit/96kHz ==> 2 channels in _or_ 2 channels out (half duplex only)
+
+ - Ai or Ao or Di or Do
+
+Important facts about the Digital interface:
+--------------------------------------------
+
+ * The Do port additionally supports surround-encoded AC-3 and DTS passthrough,
+ though I haven't tested it under Linux
+
+ - Note that in this setup only the Do interface can be enabled
+
+ * Apart from recording an audio digital stream, enabling the Di port is a way
+ to synchronize the device to an external sample clock
+
+ - As a consequence, the Di port must be enable only if an active Digital
+ source is connected
+ - Enabling Di when no digital source is connected can result in a
+ synchronization error (for instance sound played at an odd sample rate)
+
+
+Audiophile USB MIDI support in ALSA
+===================================
+
+The Audiophile USB MIDI ports will be automatically supported once the
+following modules have been loaded:
+
+ * snd-usb-audio
+ * snd-seq-midi
+
+No additional setting is required.
+
+
+Audiophile USB Audio support in ALSA
+====================================
+
+Audio functions of the Audiophile USB device are handled by the snd-usb-audio
+module. This module can work in a default mode (without any device-specific
+parameter), or in an "advanced" mode with the device-specific parameter called
+``device_setup``.
+
+Default Alsa driver mode
+------------------------
+
+The default behavior of the snd-usb-audio driver is to list the device
+capabilities at startup and activate the required mode when required
+by the applications: for instance if the user is recording in a
+24bit-depth-mode and immediately after wants to switch to a 16bit-depth mode,
+the snd-usb-audio module will reconfigure the device on the fly.
+
+This approach has the advantage to let the driver automatically switch from sample
+rates/depths automatically according to the user's needs. However, those who
+are using the device under windows know that this is not how the device is meant to
+work: under windows applications must be closed before using the m-audio control
+panel to switch the device working mode. Thus as we'll see in next section, this
+Default Alsa driver mode can lead to device misconfigurations.
+
+Let's get back to the Default Alsa driver mode for now. In this case the
+Audiophile interfaces are mapped to alsa pcm devices in the following
+way (I suppose the device's index is 1):
+
+ * hw:1,0 is Ao in playback and Di in capture
+ * hw:1,1 is Do in playback and Ai in capture
+ * hw:1,2 is Do in AC3/DTS passthrough mode
+
+In this mode, the device uses Big Endian byte-encoding so that
+supported audio format are S16_BE for 16-bit depth modes and S24_3BE for
+24-bits depth mode.
+
+One exception is the hw:1,2 port which was reported to be Little Endian
+compliant (supposedly supporting S16_LE) but processes in fact only S16_BE streams.
+This has been fixed in kernel 2.6.23 and above and now the hw:1,2 interface
+is reported to be big endian in this default driver mode.
+
+Examples:
+
+ * playing a S24_3BE encoded raw file to the Ao port::
+
+ % aplay -D hw:1,0 -c2 -t raw -r48000 -fS24_3BE test.raw
+
+ * recording a S24_3BE encoded raw file from the Ai port::
+
+ % arecord -D hw:1,1 -c2 -t raw -r48000 -fS24_3BE test.raw
+
+ * playing a S16_BE encoded raw file to the Do port::
+
+ % aplay -D hw:1,1 -c2 -t raw -r48000 -fS16_BE test.raw
+
+ * playing an ac3 sample file to the Do port::
+
+ % aplay -D hw:1,2 --channels=6 ac3_S16_BE_encoded_file.raw
+
+If you're happy with the default Alsa driver mode and don't experience any
+issue with this mode, then you can skip the following chapter.
+
+Advanced module setup
+---------------------
+
+Due to the hardware constraints described above, the device initialization made
+by the Alsa driver in default mode may result in a corrupted state of the
+device. For instance, a particularly annoying issue is that the sound captured
+from the Ai interface sounds distorted (as if boosted with an excessive high
+volume gain).
+
+For people having this problem, the snd-usb-audio module has a new module
+parameter called ``device_setup`` (this parameter was introduced in kernel
+release 2.6.17)
+
+Initializing the working mode of the Audiophile USB
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As far as the Audiophile USB device is concerned, this value let the user
+specify:
+
+ * the sample depth
+ * the sample rate
+ * whether the Di port is used or not
+
+When initialized with ``device_setup=0x00``, the snd-usb-audio module has
+the same behaviour as when the parameter is omitted (see paragraph "Default
+Alsa driver mode" above)
+
+Others modes are described in the following subsections.
+
+16-bit modes
+~~~~~~~~~~~~
+
+The two supported modes are:
+
+ * ``device_setup=0x01``
+
+ - 16bits 48kHz mode with Di disabled
+ - Ai,Ao,Do can be used at the same time
+ - hw:1,0 is not available in capture mode
+ - hw:1,2 is not available
+
+ * ``device_setup=0x11``
+
+ - 16bits 48kHz mode with Di enabled
+ - Ai,Ao,Di,Do can be used at the same time
+ - hw:1,0 is available in capture mode
+ - hw:1,2 is not available
+
+In this modes the device operates only at 16bits-modes. Before kernel 2.6.23,
+the devices where reported to be Big-Endian when in fact they were Little-Endian
+so that playing a file was a matter of using:
+::
+
+ % aplay -D hw:1,1 -c2 -t raw -r48000 -fS16_BE test_S16_LE.raw
+
+where "test_S16_LE.raw" was in fact a little-endian sample file.
+
+Thanks to Hakan Lennestal (who discovered the Little-Endiannes of the device in
+these modes) a fix has been committed (expected in kernel 2.6.23) and
+Alsa now reports Little-Endian interfaces. Thus playing a file now is as simple as
+using:

+24-bit modes
+~~~~~~~~~~~~
+
+The three supported modes are:
+
+ * ``device_setup=0x09``
+
+ - 24bits 48kHz mode with Di disabled
+ - Ai,Ao,Do can be used at the same time
+ - hw:1,0 is not available in capture mode
+ - hw:1,2 is not available
+
+ * ``device_setup=0x19``
+
+ - 24bits 48kHz mode with Di enabled
+ - 3 ports from {Ai,Ao,Di,Do} can be used at the same time
+ - hw:1,0 is available in capture mode and an active digital source must be
+ connected to Di
+ - hw:1,2 is not available
+
+ * ``device_setup=0x0D`` or ``0x10``
+
+ - 24bits 96kHz mode
+ - Di is enabled by default for this mode but does not need to be connected
+ to an active source
+ - Only 1 port from {Ai,Ao,Di,Do} can be used at the same time
+ - hw:1,0 is available in captured mode
+ - hw:1,2 is not available
+
+In these modes the device is only Big-Endian compliant (see "Default Alsa driver
+mode" above for an aplay command example)
+
+AC3 w/ DTS passthru mode
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Thanks to Hakan Lennestal, I now have a report saying that this mode works.
+
+ * ``device_setup=0x03``
+
+ - 16bits 48kHz mode with only the Do port enabled
+ - AC3 with DTS passthru
+ - Caution with this setup the Do port is mapped to the pcm device hw:1,0
+
+The command line used to playback the AC3/DTS encoded .wav-files in this mode:
+::
+
+ % aplay -D hw:1,0 --channels=6 ac3_S16_LE_encoded_file.raw
+
+How to use the ``device_setup`` parameter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The parameter can be given:
+
+ * By manually probing the device (as root):::
+
+ # modprobe -r snd-usb-audio
+ # modprobe snd-usb-audio index=1 device_setup=0x09
+
+ * Or while configuring the modules options in your modules configuration file
+ (typically a .conf file in /etc/modprobe.d/ directory:::
+
+ alias snd-card-1 snd-usb-audio
+ options snd-usb-audio index=1 device_setup=0x09
+
+CAUTION when initializing the device
+-------------------------------------
+
+ * Correct initialization on the device requires that device_setup is given to
+ the module BEFORE the device is turned on. So, if you use the "manual probing"
+ method described above, take care to power-on the device AFTER this initialization.
+
+ * Failing to respect this will lead to a misconfiguration of the device. In this case
+ turn off the device, unprobe the snd-usb-audio module, then probe it again with
+ correct device_setup parameter and then (and only then) turn on the device again.
+
+ * If you've correctly initialized the device in a valid mode and then want to switch
+ to another mode (possibly with another sample-depth), please use also the following
+ procedure:
+
+ - first turn off the device
+ - de-register the snd-usb-audio module (modprobe -r)
+ - change the device_setup parameter by changing the device_setup
+ option in ``/etc/modprobe.d/*.conf``
+ - turn on the device
+
+ * A workaround for this last issue has been applied to kernel 2.6.23, but it may not
+ be enough to ensure the 'stability' of the device initialization.
+
+Technical details for hackers
+-----------------------------
+
+This section is for hackers, wanting to understand details about the device
+internals and how Alsa supports it.
+
+Audiophile USB's ``device_setup`` structure
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to understand the device_setup magic numbers for the Audiophile
+USB, you need some very basic understanding of binary computation. However,
+this is not required to use the parameter and you may skip this section.
+
+The device_setup is one byte long and its structure is the following:
+::
+
+ +---+---+---+---+---+---+---+---+
+ | b7| b6| b5| b4| b3| b2| b1| b0|
+ +---+---+---+---+---+---+---+---+
+ | 0 | 0 | 0 | Di|24B|96K|DTS|SET|
+ +---+---+---+---+---+---+---+---+
+
+Where:
+
+ * b0 is the ``SET`` bit
+
+ - it MUST be set if device_setup is initialized
+
+ * b1 is the ``DTS`` bit
+
+ - it is set only for Digital output with DTS/AC3
+ - this setup is not tested
+
+ * b2 is the Rate selection flag
+
+ - When set to ``1`` the rate range is 48.1-96kHz
+ - Otherwise the sample rate range is 8-48kHz
+
+ * b3 is the bit depth selection flag
+
+ - When set to ``1`` samples are 24bits long
+ - Otherwise they are 16bits long
+ - Note that b2 implies b3 as the 96kHz mode is only supported for 24 bits
+ samples
+
+ * b4 is the Digital input flag
+
+ - When set to ``1`` the device assumes that an active digital source is
+ connected
+ - You shouldn't enable Di if no source is seen on the port (this leads to
+ synchronization issues)
+ - b4 is implied by b2 (since only one port is enabled at a time no synch
+ error can occur)
+
+ * b5 to b7 are reserved for future uses, and must be set to ``0``
+
+ - might become Ao, Do, Ai, for b7, b6, b4 respectively
+
+Caution:
+
+ * there is no check on the value you will give to device_setup
+
+ - for instance choosing 0x05 (16bits 96kHz) will fail back to 0x09 since
+ b2 implies b3. But _there_will_be_no_warning_ in /var/log/messages
+
+ * Hardware constraints due to the USB bus limitation aren't checked
+
+ - choosing b2 will prepare all interfaces for 24bits/96kHz but you'll
+ only be able to use one at the same time
+
+USB implementation details for this device
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You may safely skip this section if you're not interested in driver
+hacking.
+
+This section describes some internal aspects of the device and summarizes the
+data I got by usb-snooping the windows and Linux drivers.
+
+The M-Audio Audiophile USB has 7 USB Interfaces:
+a "USB interface":
+
+ * USB Interface nb.0
+ * USB Interface nb.1
+
+ - Audio Control function
+
+ * USB Interface nb.2
+
+ - Analog Output
+
+ * USB Interface nb.3
+
+ - Digital Output
+
+ * USB Interface nb.4
+
+ - Analog Input
+
+ * USB Interface nb.5
+
+ - Digital Input
+
+ * USB Interface nb.6
+
+ - MIDI interface compliant with the MIDIMAN quirk
+
+Each interface has 5 altsettings (AltSet 1,2,3,4,5) except:
+
+ * Interface 3 (Digital Out) has an extra Alset nb.6
+ * Interface 5 (Digital In) does not have Alset nb.3 and 5
+
+Here is a short description of the AltSettings capabilities:
+
+* AltSettings 1 corresponds to
+
+ - 24-bit depth, 48.1-96kHz sample mode
+ - Adaptive playback (Ao and Do), Synch capture (Ai), or Asynch capture (Di)
+
+* AltSettings 2 corresponds to
+
+ - 24-bit depth, 8-48kHz sample mode
+ - Asynch capture and playback (Ao,Ai,Do,Di)
+
+* AltSettings 3 corresponds to
+
+ - 24-bit depth, 8-48kHz sample mode
+ - Synch capture (Ai) and Adaptive playback (Ao,Do)
+
+* AltSettings 4 corresponds to
+
+ - 16-bit depth, 8-48kHz sample mode
+ - Asynch capture and playback (Ao,Ai,Do,Di)
+
+* AltSettings 5 corresponds to
+
+ - 16-bit depth, 8-48kHz sample mode
+ - Synch capture (Ai) and Adaptive playback (Ao,Do)
+
+* AltSettings 6 corresponds to
+
+ - 16-bit depth, 8-48kHz sample mode
+ - Synch playback (Do), audio format type III IEC1937_AC-3
+
+In order to ensure a correct initialization of the device, the driver
+*must* *know* how the device will be used:
+
+ * if DTS is chosen, only Interface 2 with AltSet nb.6 must be
+ registered
+ * if 96KHz only AltSets nb.1 of each interface must be selected
+ * if samples are using 24bits/48KHz then AltSet 2 must me used if
+ Digital input is connected, and only AltSet nb.3 if Digital input
+ is not connected
+ * if samples are using 16bits/48KHz then AltSet 4 must me used if
+ Digital input is connected, and only AltSet nb.5 if Digital input
+ is not connected
+
+When device_setup is given as a parameter to the snd-usb-audio module, the
+parse_audio_endpoints function uses a quirk called
+``audiophile_skip_setting_quirk`` in order to prevent AltSettings not
+corresponding to device_setup from being registered in the driver.
+
+Audiophile USB and Jack support
+===============================
+
+This section deals with support of the Audiophile USB device in Jack.
+
+There are 2 main potential issues when using Jackd with the device:
+
+* support for Big-Endian devices in 24-bit modes
+* support for 4-in / 4-out channels
+
+Direct support in Jackd
+-----------------------
+
+Jack supports big endian devices only in recent versions (thanks to
+Andreas Steinmetz for his first big-endian patch). I can't remember
+exactly when this support was released into jackd, let's just say that
+with jackd version 0.103.0 it's almost ok (just a small bug is affecting
+16bits Big-Endian devices, but since you've read carefully the above
+paragraphs, you're now using kernel >= 2.6.23 and your 16bits devices
+are now Little Endians ;-) ).
+
+You can run jackd with the following command for playback with Ao and
+record with Ai:
+::
+
+ % jackd -R -dalsa -Phw:1,0 -r48000 -p128 -n2 -D -Chw:1,1
+
+Using Alsa plughw
+-----------------
+
+If you don't have a recent Jackd installed, you can downgrade to using
+the Alsa ``plug`` converter.
+
+For instance here is one way to run Jack with 2 playback channels on Ao and 2
+capture channels from Ai:
+::
+
+ % jackd -R -dalsa -dplughw:1 -r48000 -p256 -n2 -D -Cplughw:1,1
+
+However you may see the following warning message:
+ You appear to be using the ALSA software "plug" layer, probably a result of
+ using the "default" ALSA device. This is less efficient than it could be.
+ Consider using a hardware device instead rather than using the plug layer.
+
+Getting 2 input and/or output interfaces in Jack
+------------------------------------------------
+
+As you can see, starting the Jack server this way will only enable 1 stereo
+input (Di or Ai) and 1 stereo output (Ao or Do).
+
+This is due to the following restrictions:
+
+* Jack can only open one capture device and one playback device at a time
+* The Audiophile USB is seen as 2 (or three) Alsa devices: hw:1,0, hw:1,1
+ (and optionally hw:1,2)
+
+If you want to get Ai+Di and/or Ao+Do support with Jack, you would need to
+combine the Alsa devices into one logical "complex" device.
+
+If you want to give it a try, I recommend reading the information from
+this page: http://www.sound-man.co.uk/linuxaudio/ice1712multi.html
+It is related to another device (ice1712) but can be adapted to suit
+the Audiophile USB.
+
+Enabling multiple Audiophile USB interfaces for Jackd will certainly require:
+
+* Making sure your Jackd version has the MMAP_COMPLEX patch (see the ice1712 page)
+* (maybe) patching the alsa-lib/src/pcm/pcm_multi.c file (see the ice1712 page)
+* define a multi device (combination of hw:1,0 and hw:1,1) in your .asoundrc
+ file
+* start jackd with this device
+
+I had no success in testing this for now, if you have any success with this kind
+of setup, please drop me an email.

+=================
+ALSA BT87x Driver
+=================
+
+Intro
+=====
+
+You might have noticed that the bt878 grabber cards have actually
+*two* PCI functions:
+::
+
+ $ lspci
+ [ ... ]
+ 00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
+ 00:0a.1 Multimedia controller: Brooktree Corporation Bt878 (rev 02)
+ [ ... ]
+
+The first does video, it is backward compatible to the bt848. The second
+does audio. snd-bt87x is a driver for the second function. It's a sound
+driver which can be used for recording sound (and *only* recording, no
+playback). As most TV cards come with a short cable which can be plugged
+into your sound card's line-in you probably don't need this driver if all
+you want to do is just watching TV...
+
+Some cards do not bother to connect anything to the audio input pins of
+the chip, and some other cards use the audio function to transport MPEG
+video data, so it's quite possible that audio recording may not work
+with your card.
+
+
+Driver Status
+=============
+
+The driver is now stable. However, it doesn't know about many TV cards,
+and it refuses to load for cards it doesn't know.
+
+If the driver complains ("Unknown TV card found, the audio driver will
+not load"), you can specify the ``load_all=1`` option to force the driver to
+try to use the audio capture function of your card. If the frequency of
+recorded data is not right, try to specify the ``digital_rate`` option with
+other values than the default 32000 (often it's 44100 or 64000).
+
+If you have an unknown card, please mail the ID and board name to
+<alsa-devel@alsa-project.org>, regardless of whether audio capture works
+or not, so that future versions of this driver know about your card.
+
+
+Audio modes
+===========
+
+The chip knows two different modes (digital/analog). snd-bt87x
+registers two PCM devices, one for each mode. They cannot be used at
+the same time.
+
+
+Digital audio mode
+==================
+
+The first device (hw:X,0) gives you 16 bit stereo sound. The sample
+rate depends on the external source which feeds the Bt87x with digital
+sound via I2S interface.
+
+
+Analog audio mode (A/D)
+=======================
+
+The second device (hw:X,1) gives you 8 or 16 bit mono sound. Supported
+sample rates are between 119466 and 448000 Hz (yes, these numbers are
+that high). If you've set the CONFIG_SND_BT87X_OVERCLOCK option, the
+maximum sample rate is 1792000 Hz, but audio data becomes unusable
+beyond 896000 Hz on my card.
+
+The chip has three analog inputs. Consequently you'll get a mixer
+device to control these.
+
+
+Have fun,
+

+Brief Notes on C-Media 8338/8738/8768/8770 Driver
+=================================================
+
+Takashi Iwai <tiwai@suse.de>
+
+
+Front/Rear Multi-channel Playback
+---------------------------------
+
+CM8x38 chip can use ADC as the second DAC so that two different stereo
+channels can be used for front/rear playbacks. Since there are two
+DACs, both streams are handled independently unlike the 4/6ch multi-
+channel playbacks in the section below.
+
+As default, ALSA driver assigns the first PCM device (i.e. hw:0,0 for
+card#0) for front and 4/6ch playbacks, while the second PCM device
+(hw:0,1) is assigned to the second DAC for rear playback.
+
+There are slight differences between the two DACs:
+
+- The first DAC supports U8 and S16LE formats, while the second DAC
+ supports only S16LE.
+- The second DAC supports only two channel stereo.
+
+Please note that the CM8x38 DAC doesn't support continuous playback
+rate but only fixed rates: 5512, 8000, 11025, 16000, 22050, 32000,
+44100 and 48000 Hz.
+
+The rear output can be heard only when "Four Channel Mode" switch is
+disabled. Otherwise no signal will be routed to the rear speakers.
+As default it's turned on.
+
+.. WARNING::
+ When "Four Channel Mode" switch is off, the output from rear speakers
+ will be FULL VOLUME regardless of Master and PCM volumes [#]_.
+ This might damage your audio equipment. Please disconnect speakers
+ before your turn off this switch.
+
+
+.. [#]
+ Well.. I once got the output with correct volume (i.e. same with the
+ front one) and was so excited. It was even with "Four Channel" bit
+ on and "double DAC" mode. Actually I could hear separate 4 channels
+ from front and rear speakers! But.. after reboot, all was gone.
+ It's a very pity that I didn't save the register dump at that
+ time.. Maybe there is an unknown register to achieve this...
+
+If your card has an extra output jack for the rear output, the rear
+playback should be routed there as default. If not, there is a
+control switch in the driver "Line-In As Rear", which you can change
+via alsamixer or somewhat else. When this switch is on, line-in jack
+is used as rear output.
+
+There are two more controls regarding to the rear output.
+The "Exchange DAC" switch is used to exchange front and rear playback
+routes, i.e. the 2nd DAC is output from front output.
+
+
+4/6 Multi-Channel Playback
+--------------------------
+
+The recent CM8738 chips support for the 4/6 multi-channel playback
+function. This is useful especially for AC3 decoding.
+
+When the multi-channel is supported, the driver name has a suffix
+"-MC" such like "CMI8738-MC6". You can check this name from
+/proc/asound/cards.
+
+When the 4/6-ch output is enabled, the second DAC accepts up to 6 (or
+4) channels. While the dual DAC supports two different rates or
+formats, the 4/6-ch playback supports only the same condition for all
+channels. Since the multi-channel playback mode uses both DACs, you
+cannot operate with full-duplex.
+
+The 4.0 and 5.1 modes are defined as the pcm "surround40" and "surround51"
+in alsa-lib. For example, you can play a WAV file with 6 channels like
+::
+
+ % aplay -Dsurround51 sixchannels.wav
+
+For programming the 4/6 channel playback, you need to specify the PCM
+channels as you like and set the format S16LE. For example, for playback
+with 4 channels,
+::
+
+ snd_pcm_hw_params_set_access(pcm, hw, SND_PCM_ACCESS_RW_INTERLEAVED);
+ // or mmap if you like
+ snd_pcm_hw_params_set_format(pcm, hw, SND_PCM_FORMAT_S16_LE);
+ snd_pcm_hw_params_set_channels(pcm, hw, 4);
+
+and use the interleaved 4 channel data.
+
+There are some control switches affecting to the speaker connections:
+
+Line-In Mode
+ an enum control to change the behavior of line-in
+ jack. Either "Line-In", "Rear Output" or "Bass Output" can
+ be selected. The last item is available only with model 039
+ or newer.
+ When "Rear Output" is chosen, the surround channels 3 and 4
+ are output to line-in jack.
+Mic-In Mode
+ an enum control to change the behavior of mic-in
+ jack. Either "Mic-In" or "Center/LFE Output" can be
+ selected.
+ When "Center/LFE Output" is chosen, the center and bass
+ channels (channels 5 and 6) are output to mic-in jack.
+
+Digital I/O
+-----------
+
+The CM8x38 provides the excellent SPDIF capability with very cheap
+price (yes, that's the reason I bought the card :)
+
+The SPDIF playback and capture are done via the third PCM device
+(hw:0,2). Usually this is assigned to the PCM device "spdif".
+The available rates are 44100 and 48000 Hz.
+For playback with aplay, you can run like below:
+::
+
+ % aplay -Dhw:0,2 foo.wav
+
+or
+
+::
+
+ % aplay -Dspdif foo.wav
+
+24bit format is also supported experimentally.
+
+The playback and capture over SPDIF use normal DAC and ADC,
+respectively, so you cannot playback both analog and digital streams
+simultaneously.
+
+To enable SPDIF output, you need to turn on "IEC958 Output Switch"
+control via mixer or alsactl ("IEC958" is the official name of
+so-called S/PDIF). Then you'll see the red light on from the card so
+you know that's working obviously :)
+The SPDIF input is always enabled, so you can hear SPDIF input data
+from line-out with "IEC958 In Monitor" switch at any time (see
+below).
+
+You can play via SPDIF even with the first device (hw:0,0),
+but SPDIF is enabled only when the proper format (S16LE), sample rate
+(441100 or 48000) and channels (2) are used. Otherwise it's turned
+off. (Also don't forget to turn on "IEC958 Output Switch", too.)
+
+
+Additionally there are relevant control switches:
+
+IEC958 Mix Analog
+ Mix analog PCM playback and FM-OPL/3 streams and
+ output through SPDIF. This switch appears only on old chip
+ models (CM8738 033 and 037).
+
+ Note: without this control you can output PCM to SPDIF.
+ This is "mixing" of streams, so e.g. it's not for AC3 output
+ (see the next section).
+
+IEC958 In Select
+ Select SPDIF input, the internal CD-in (false)
+ and the external input (true).
+
+IEC958 Loop
+ SPDIF input data is loop back into SPDIF
+ output (aka bypass)
+
+IEC958 Copyright
+ Set the copyright bit.
+
+IEC958 5V
+ Select 0.5V (coax) or 5V (optical) interface.
+ On some cards this doesn't work and you need to change the
+ configuration with hardware dip-switch.
+
+IEC958 In Monitor
+ SPDIF input is routed to DAC.
+
+IEC958 In Phase Inverse
+ Set SPDIF input format as inverse.
+ [FIXME: this doesn't work on all chips..]
+
+IEC958 In Valid
+ Set input validity flag detection.
+
+Note: When "PCM Playback Switch" is on, you'll hear the digital output
+stream through analog line-out.
+
+
+The AC3 (RAW DIGITAL) OUTPUT
+----------------------------
+
+The driver supports raw digital (typically AC3) i/o over SPDIF. This
+can be toggled via IEC958 playback control, but usually you need to
+access it via alsa-lib. See alsa-lib documents for more details.
+
+On the raw digital mode, the "PCM Playback Switch" is automatically
+turned off so that non-audio data is heard from the analog line-out.
+Similarly the following switches are off: "IEC958 Mix Analog" and
+"IEC958 Loop". The switches are resumed after closing the SPDIF PCM
+device automatically to the previous state.
+
+On the model 033, AC3 is implemented by the software conversion in
+the alsa-lib. If you need to bypass the software conversion of IEC958
+subframes, pass the "soft_ac3=0" module option. This doesn't matter
+on the newer models.
+
+
+ANALOG MIXER INTERFACE
+----------------------
+
+The mixer interface on CM8x38 is similar to SB16.
+There are Master, PCM, Synth, CD, Line, Mic and PC Speaker playback
+volumes. Synth, CD, Line and Mic have playback and capture switches,
+too, as well as SB16.
+
+In addition to the standard SB mixer, CM8x38 provides more functions.
+- PCM playback switch
+- PCM capture switch (to capture the data sent to DAC)
+- Mic Boost switch
+- Mic capture volume
+- Aux playback volume/switch and capture switch
+- 3D control switch
+
+
+MIDI CONTROLLER
+---------------
+
+With CMI8338 chips, the MPU401-UART interface is disabled as default.
+You need to set the module option "mpu_port" to a valid I/O port address
+to enable MIDI support. Valid I/O ports are 0x300, 0x310, 0x320 and
+0x330. Choose a value that doesn't conflict with other cards.
+
+With CMI8738 and newer chips, the MIDI interface is enabled by default
+and the driver automatically chooses a port address.
+
+There is *no* hardware wavetable function on this chip (except for
+OPL3 synth below).
+What's said as MIDI synth on Windows is a software synthesizer
+emulation. On Linux use TiMidity or other softsynth program for
+playing MIDI music.
+
+
+FM OPL/3 Synth
+--------------
+
+The FM OPL/3 is also enabled as default only for the first card.
+Set "fm_port" module option for more cards.
+
+The output quality of FM OPL/3 is, however, very weird.
+I don't know why..
+
+CMI8768 and newer chips do not have the FM synth.
+
+
+Joystick and Modem
+------------------
+
+The legacy joystick is supported. To enable the joystick support, pass
+joystick_port=1 module option. The value 1 means the auto-detection.
+If the auto-detection fails, try to pass the exact I/O address.
+
+The modem is enabled dynamically via a card control switch "Modem".
+
+
+Debugging Information
+---------------------
+
+The registers are shown in /proc/asound/cardX/cmipci. If you have any
+problem (especially unexpected behavior of mixer), please attach the
+output of this proc file together with the bug report.

+Low latency, multichannel audio with JACK and the emu10k1/emu10k2
+=================================================================
+
+This document is a guide to using the emu10k1 based devices with JACK for low
+latency, multichannel recording functionality. All of my recent work to allow
+Linux users to use the full capabilities of their hardware has been inspired
+by the kX Project. Without their work I never would have discovered the true
+power of this hardware.
+
+ http://www.kxproject.com
+ - Lee Revell, 2005.03.30
+
+
+Until recently, emu10k1 users on Linux did not have access to the same low
+latency, multichannel features offered by the "kX ASIO" feature of their
+Windows driver. As of ALSA 1.0.9 this is no more!
+
+For those unfamiliar with kX ASIO, this consists of 16 capture and 16 playback
+channels. With a post 2.6.9 Linux kernel, latencies down to 64 (1.33 ms) or
+even 32 (0.66ms) frames should work well.
+
+The configuration is slightly more involved than on Windows, as you have to
+select the correct device for JACK to use. Actually, for qjackctl users it's
+fairly self explanatory - select Duplex, then for capture and playback select
+the multichannel devices, set the in and out channels to 16, and the sample
+rate to 48000Hz. The command line looks like this:
+::
+
+ /usr/local/bin/jackd -R -dalsa -r48000 -p64 -n2 -D -Chw:0,2 -Phw:0,3 -S
+
+This will give you 16 input ports and 16 output ports.
+
+The 16 output ports map onto the 16 FX buses (or the first 16 of 64, for the
+Audigy). The mapping from FX bus to physical output is described in
+sb-live-mixer.rst (or audigy-mixer.rst).
+
+The 16 input ports are connected to the 16 physical inputs. Contrary to
+popular belief, all emu10k1 cards are multichannel cards. Which of these
+input channels have physical inputs connected to them depends on the card
+model. Trial and error is highly recommended; the pinout diagrams
+for the card have been reverse engineered by some enterprising kX users and are
+available on the internet. Meterbridge is helpful here, and the kX forums are
+packed with useful information.
+
+Each input port will either correspond to a digital (SPDIF) input, an analog
+input, or nothing. The one exception is the SBLive! 5.1. On these devices,
+the second and third input ports are wired to the center/LFE output. You will
+still see 16 capture channels, but only 14 are available for recording inputs.
+
+This chart, borrowed from kxfxlib/da_asio51.cpp, describes the mapping of JACK
+ports to FXBUS2 (multitrack recording input) and EXTOUT (physical output)
+channels.

+Software Interface ALSA-DSP MADI Driver
+=======================================
+
+(translated from German, so no good English ;-),
+
+2004 - winfried ritsch
+
+
+Full functionality has been added to the driver. Since some of
+the Controls and startup-options are ALSA-Standard and only the
+special Controls are described and discussed below.
+
+
+Hardware functionality
+======================
+
+Audio transmission
+------------------
+
+* number of channels -- depends on transmission mode
+
+ The number of channels chosen is from 1..Nmax. The reason to
+ use for a lower number of channels is only resource allocation,
+ since unused DMA channels are disabled and less memory is
+ allocated. So also the throughput of the PCI system can be
+ scaled. (Only important for low performance boards).
+
+* Single Speed -- 1..64 channels
+
+.. note::
+ (Note: Choosing the 56channel mode for transmission or as
+ receiver, only 56 are transmitted/received over the MADI, but
+ all 64 channels are available for the mixer, so channel count
+ for the driver)
+
+* Double Speed -- 1..32 channels
+
+.. note::
+ Note: Choosing the 56-channel mode for
+ transmission/receive-mode , only 28 are transmitted/received
+ over the MADI, but all 32 channels are available for the mixer,
+ so channel count for the driver
+
+
+* Quad Speed -- 1..16 channels
+
+.. note::
+ Choosing the 56-channel mode for
+ transmission/receive-mode , only 14 are transmitted/received
+ over the MADI, but all 16 channels are available for the mixer,
+ so channel count for the driver
+
+* Format -- signed 32 Bit Little Endian (SNDRV_PCM_FMTBIT_S32_LE)
+
+* Sample Rates --
+
+ Single Speed -- 32000, 44100, 48000
+
+ Double Speed -- 64000, 88200, 96000 (untested)
+
+ Quad Speed -- 128000, 176400, 192000 (untested)
+
+* access-mode -- MMAP (memory mapped), Not interleaved (PCM_NON-INTERLEAVED)
+
+* buffer-sizes -- 64,128,256,512,1024,2048,8192 Samples
+
+* fragments -- 2
+
+* Hardware-pointer -- 2 Modi
+
+
+ The Card supports the readout of the actual Buffer-pointer,
+ where DMA reads/writes. Since of the bulk mode of PCI it is only
+ 64 Byte accurate. SO it is not really usable for the
+ ALSA-mid-level functions (here the buffer-ID gives a better
+ result), but if MMAP is used by the application. Therefore it
+ can be configured at load-time with the parameter
+ precise-pointer.
+
+
+.. hint::
+ (Hint: Experimenting I found that the pointer is maximum 64 to
+ large never to small. So if you subtract 64 you always have a
+ safe pointer for writing, which is used on this mode inside
+ ALSA. In theory now you can get now a latency as low as 16
+ Samples, which is a quarter of the interrupt possibilities.)
+
+ * Precise Pointer -- off
+ interrupt used for pointer-calculation
+
+ * Precise Pointer -- on
+ hardware pointer used.
+
+Controller
+----------
+
+Since DSP-MADI-Mixer has 8152 Fader, it does not make sense to
+use the standard mixer-controls, since this would break most of
+(especially graphic) ALSA-Mixer GUIs. So Mixer control has be
+provided by a 2-dimensional controller using the
+hwdep-interface.
+
+Also all 128+256 Peak and RMS-Meter can be accessed via the
+hwdep-interface. Since it could be a performance problem always
+copying and converting Peak and RMS-Levels even if you just need
+one, I decided to export the hardware structure, so that of
+needed some driver-guru can implement a memory-mapping of mixer
+or peak-meters over ioctl, or also to do only copying and no
+conversion. A test-application shows the usage of the controller.
+
+* Latency Controls --- not implemented !!!
+
+.. note::
+ Note: Within the windows-driver the latency is accessible of a
+ control-panel, but buffer-sizes are controlled with ALSA from
+ hwparams-calls and should not be changed in run-state, I did not
+ implement it here.
+

+
+ * Access -- Read Write

+ * Values -- "Master" "Slave"
+
+.. note::
+ !!!! This is a hardware-function but is in conflict with the
+ Clock-source controller, which is a kind of ALSA-standard. I
+ makes sense to set the card to a special mode (master at some
+ frequency or slave), since even not using an Audio-application
+ a studio should have working synchronisations setup. So use
+ Clock-source-controller instead !!!!

+
+ Choose between Master at a specific Frequency and so also the
+ Speed-mode or Slave (Autosync). Also see "Preferred Sync Ref"
+
+.. warning::

+ ALSA by some ALSA-drivers before, so I use it also. !!!
+
+
+* Preferred Sync Ref
+
+ * Name -- "Preferred Sync Reference"
+
+ * Access -- Read Write
+
+ * Values -- "Word" "MADI"
+
+
+ Within the Auto-sync-Mode the preferred Sync Source can be
+ chosen. If it is not available another is used if possible.
+
+.. note::
+ Note: Since MADI has a much higher bit-rate than word-clock, the
+ card should synchronise better in MADI Mode. But since the
+ RME-PLL is very good, there are almost no problems with
+ word-clock too. I never found a difference.

+=======================================
+Analog Joystick Support on ALSA Drivers
+=======================================
+
+Oct. 14, 2003
+
+Takashi Iwai <tiwai@suse.de>
+
+General
+-------
+
+First of all, you need to enable GAMEPORT support on Linux kernel for
+using a joystick with the ALSA driver. For the details of gameport
+support, refer to Documentation/input/joydev/joystick.rst.
+
+The joystick support of ALSA drivers is different between ISA and PCI
+cards. In the case of ISA (PnP) cards, it's usually handled by the
+independent module (ns558). Meanwhile, the ALSA PCI drivers have the
+built-in gameport support. Hence, when the ALSA PCI driver is built
+in the kernel, CONFIG_GAMEPORT must be 'y', too. Otherwise, the
+gameport support on that card will be (silently) disabled.
+
+Some adapter modules probe the physical connection of the device at
+the load time. It'd be safer to plug in the joystick device before
+loading the module.
+
+
+PCI Cards
+---------
+
+For PCI cards, the joystick is enabled when the appropriate module
+option is specified. Some drivers don't need options, and the
+joystick support is always enabled. In the former ALSA version, there
+was a dynamic control API for the joystick activation. It was
+changed, however, to the static module options because of the system
+stability and the resource management.
+
+The following PCI drivers support the joystick natively.
+
+============== ============= ============================================
+Driver Module Option Available Values
+============== ============= ============================================
+als4000 joystick_port 0 = disable (default), 1 = auto-detect,
+ manual: any address (e.g. 0x200)

+via82xx [#f1]_ joystick 0 = disable (default), 1 = enable
+ymfpci joystick_port 0 = disable (default), 1 = auto-detect,
+ manual: 0x201, 0x202, 0x204, 0x205 [#f2]_
+============== ============= ============================================
+
+.. [#f1] VIA686A/B only
+.. [#f2] With YMF744/754 chips, the port address can be chosen arbitrarily
+
+The following drivers don't support gameport natively, but there are
+additional modules. Load the corresponding module to add the gameport
+support.
+
+======= =================
+Driver Additional Module
+======= =================
+emu10k1 emu10k1-gp
+fm801 fm801-gp
+======= =================
+
+Note: the "pcigame" and "cs461x" modules are for the OSS drivers only.
+These ALSA drivers (cs46xx, trident and au88x0) have the
+built-in gameport support.
+
+As mentioned above, ALSA PCI drivers have the built-in gameport
+support, so you don't have to load ns558 module. Just load "joydev"
+and the appropriate adapter module (e.g. "analog").
+
+
+ISA Cards
+---------
+
+ALSA ISA drivers don't have the built-in gameport support.
+Instead, you need to load "ns558" module in addition to "joydev" and
+the adapter module (e.g. "analog").

+Notes on Maya44 USB Audio Support
+=================================
+
+.. note::
+ The following is the original document of Rainer's patch that the
+ current maya44 code based on. Some contents might be obsoleted, but I
+ keep here as reference -- tiwai
+
+Feb 14, 2008
+
+Rainer Zimmermann <mail@lightshed.de>
+
+STATE OF DEVELOPMENT
+====================
+
+This driver is being developed on the initiative of Piotr Makowski (oponek@gmail.com) and financed by Lars Bergmann.
+Development is carried out by Rainer Zimmermann (mail@lightshed.de).
+
+ESI provided a sample Maya44 card for the development work.
+
+However, unfortunately it has turned out difficult to get detailed programming information, so I (Rainer Zimmermann) had to find out some card-specific information by experiment and conjecture. Some information (in particular, several GPIO bits) is still missing.
+
+This is the first testing version of the Maya44 driver released to the alsa-devel mailing list (Feb 5, 2008).
+
+
+The following functions work, as tested by Rainer Zimmermann and Piotr Makowski:
+
+- playback and capture at all sampling rates
+- input/output level
+- crossmixing
+- line/mic switch
+- phantom power switch
+- analogue monitor a.k.a bypass
+
+
+The following functions *should* work, but are not fully tested:
+
+- Channel 3+4 analogue - S/PDIF input switching
+- S/PDIF output
+- all inputs/outputs on the M/IO/DIO extension card
+- internal/external clock selection
+
+
+*In particular, we would appreciate testing of these functions by anyone who has access to an M/IO/DIO extension card.*
+
+
+Things that do not seem to work:
+
+- The level meters ("multi track") in 'alsamixer' do not seem to react to signals in (if this is a bug, it would probably be in the existing ICE1724 code).
+
+- Ardour 2.1 seems to work only via JACK, not using ALSA directly or via OSS. This still needs to be tracked down.
+
+
+DRIVER DETAILS
+==============
+
+the following files were added:
+
+* pci/ice1724/maya44.c - Maya44 specific code
+* pci/ice1724/maya44.h
+* pci/ice1724/ice1724.patch
+* pci/ice1724/ice1724.h.patch - PROPOSED patch to ice1724.h (see SAMPLING RATES)
+* i2c/other/wm8776.c - low-level access routines for Wolfson WM8776 codecs
+* include/wm8776.h
+
+
+Note that the wm8776.c code is meant to be card-independent and does not actually register the codec with the ALSA infrastructure.
+This is done in maya44.c, mainly because some of the WM8776 controls are used in Maya44-specific ways, and should be named appropriately.
+
+
+the following files were created in pci/ice1724, simply #including the corresponding file from the alsa-kernel tree:
+
+* wtm.h
+* vt1720_mobo.h
+* revo.h
+* prodigy192.h
+* pontis.h
+* phase.h
+* maya44.h
+* juli.h
+* aureon.h
+* amp.h
+* envy24ht.h
+* se.h
+* prodigy_hifi.h
+
+
+*I hope this is the correct way to do things.*
+
+
+SAMPLING RATES
+==============
+
+The Maya44 card (or more exactly, the Wolfson WM8776 codecs) allow a maximum sampling rate of 192 kHz for playback and 92 kHz for capture.
+
+As the ICE1724 chip only allows one global sampling rate, this is handled as follows:
+
+* setting the sampling rate on any open PCM device on the maya44 card will always set the *global* sampling rate for all playback and capture channels.
+
+* In the current state of the driver, setting rates of up to 192 kHz is permitted even for capture devices.
+
+*AVOID CAPTURING AT RATES ABOVE 96kHz*, even though it may appear to work. The codec cannot actually capture at such rates, meaning poor quality.
+
+
+I propose some additional code for limiting the sampling rate when setting on a capture pcm device. However because of the global sampling rate, this logic would be somewhat problematic.
+
+The proposed code (currently deactivated) is in ice1712.h.patch, ice1724.c and maya44.c (in pci/ice1712).
+
+
+SOUND DEVICES
+=============
+
+PCM devices correspond to inputs/outputs as follows (assuming Maya44 is card #0):
+
+* hw:0,0 input - stereo, analog input 1+2
+* hw:0,0 output - stereo, analog output 1+2
+* hw:0,1 input - stereo, analog input 3+4 OR S/PDIF input
+* hw:0,1 output - stereo, analog output 3+4 (and SPDIF out)
+
+
+NAMING OF MIXER CONTROLS
+========================
+
+(for more information about the signal flow, please refer to the block diagram on p.24 of the ESI Maya44 manual, or in the ESI windows software).
+
+
+PCM
+ (digital) output level for channel 1+2
+PCM 1
+ same for channel 3+4
+
+Mic Phantom+48V
+ switch for +48V phantom power for electrostatic microphones on input 1/2.
+
+ Make sure this is not turned on while any other source is connected to input 1/2.
+ It might damage the source and/or the maya44 card.
+
+Mic/Line input
+ if switch is on, input jack 1/2 is microphone input (mono), otherwise line input (stereo).
+
+Bypass
+ analogue bypass from ADC input to output for channel 1+2. Same as "Monitor" in the windows driver.
+Bypass 1
+ same for channel 3+4.
+
+Crossmix
+ cross-mixer from channels 1+2 to channels 3+4
+Crossmix 1
+ cross-mixer from channels 3+4 to channels 1+2
+
+IEC958 Output
+ switch for S/PDIF output.
+
+ This is not supported by the ESI windows driver.
+ S/PDIF should output the same signal as channel 3+4. [untested!]
+
+
+Digitial output selectors
+ These switches allow a direct digital routing from the ADCs to the DACs.
+ Each switch determines where the digital input data to one of the DACs comes from.
+ They are not supported by the ESI windows driver.
+ For normal operation, they should all be set to "PCM out".
+
+H/W
+ Output source channel 1
+H/W 1
+ Output source channel 2
+H/W 2
+ Output source channel 3
+H/W 3
+ Output source channel 4
+
+H/W 4 ... H/W 9
+ unknown function, left in to enable testing.
+
+ Possibly some of these control S/PDIF output(s).
+ If these turn out to be unused, they will go away in later driver versions.
+
+Selectable values for each of the digital output selectors are:
+
+PCM out
+ DAC output of the corresponding channel (default setting)
+Input 1 ... Input 4
+ direct routing from ADC output of the selected input channel

+==============================================================
+Alsa driver for Digigram miXart8 and miXart8AES/EBU soundcards
+==============================================================
+
+Digigram <alsa@digigram.com>
+
+
+GENERAL
+=======
+
+The miXart8 is a multichannel audio processing and mixing soundcard
+that has 4 stereo audio inputs and 4 stereo audio outputs.
+The miXart8AES/EBU is the same with a add-on card that offers further
+4 digital stereo audio inputs and outputs.
+Furthermore the add-on card offers external clock synchronisation
+(AES/EBU, Word Clock, Time Code and Video Synchro)
+
+The mainboard has a PowerPC that offers onboard mpeg encoding and
+decoding, samplerate conversions and various effects.
+
+The driver don't work properly at all until the certain firmwares
+are loaded, i.e. no PCM nor mixer devices will appear.
+Use the mixartloader that can be found in the alsa-tools package.
+
+
+VERSION 0.1.0
+=============
+
+One miXart8 board will be represented as 4 alsa cards, each with 1
+stereo analog capture 'pcm0c' and 1 stereo analog playback 'pcm0p' device.
+With a miXart8AES/EBU there is in addition 1 stereo digital input
+'pcm1c' and 1 stereo digital output 'pcm1p' per card.
+
+Formats
+-------
+U8, S16_LE, S16_BE, S24_3LE, S24_3BE, FLOAT_LE, FLOAT_BE
+Sample rates : 8000 - 48000 Hz continuously
+
+Playback
+--------
+For instance the playback devices are configured to have max. 4
+substreams performing hardware mixing. This could be changed to a
+maximum of 24 substreams if wished.
+Mono files will be played on the left and right channel. Each channel
+can be muted for each stream to use 8 analog/digital outputs separately.
+
+Capture
+-------
+There is one substream per capture device. For instance only stereo
+formats are supported.
+
+Mixer
+-----
+<Master> and <Master Capture>
+ analog volume control of playback and capture PCM.
+<PCM 0-3> and <PCM Capture>
+ digital volume control of each analog substream.
+<AES 0-3> and <AES Capture>
+ digital volume control of each AES/EBU substream.
+<Monitoring>
+ Loopback from 'pcm0c' to 'pcm0p' with digital volume
+ and mute control.
+
+Rem : for best audio quality try to keep a 0 attenuation on the PCM
+and AES volume controls which is set by 219 in the range from 0 to 255
+(about 86% with alsamixer)
+
+
+NOT YET IMPLEMENTED
+===================
+
+- external clock support (AES/EBU, Word Clock, Time Code, Video Sync)
+- MPEG audio formats
+- mono record
+- on-board effects and samplerate conversions
+- linked streams
+
+
+FIRMWARE
+========
+
+[As of 2.6.11, the firmware can be loaded automatically with hotplug
+ when CONFIG_FW_LOADER is set. The mixartloader is necessary only
+ for older versions or when you build the driver into kernel.]
+
+For loading the firmware automatically after the module is loaded, use a
+install command. For example, add the following entry to
+/etc/modprobe.d/mixart.conf for miXart driver:
+::
+
+ install snd-mixart /sbin/modprobe --first-time -i snd-mixart && \
+ /usr/bin/mixartloader
+
+
+(for 2.2/2.4 kernels, add "post-install snd-mixart /usr/bin/vxloader" to
+/etc/modules.conf, instead.)
+
+The firmware binaries are installed on /usr/share/alsa/firmware
+(or /usr/local/share/alsa/firmware, depending to the prefix option of
+configure). There will be a miXart.conf file, which define the dsp image
+files.
+

+# Turtle Beach MultiSound Driver Notes
+# -- Andrew Veliath <andrewtv@usa.net>
+#
+# Last update: September 10, 1998
+# Corresponding msnd driver: 0.8.3
+#
+# ** This file is a README (top part) and shell archive (bottom part).
+# The corresponding archived utility sources can be unpacked by
+# running `sh MultiSound' (the utilities are only needed for the
+# Pinnacle and Fiji cards). **
+#
+#
+# -=-=- Getting Firmware -=-=-
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# See the section `Obtaining and Creating Firmware Files' in this
+# document for instructions on obtaining the necessary firmware
+# files.
+#
+#
+# Supported Features
+# ~~~~~~~~~~~~~~~~~~
+#
+# Currently, full-duplex digital audio (/dev/dsp only, /dev/audio is
+# not currently available) and mixer functionality (/dev/mixer) are
+# supported (memory mapped digital audio is not yet supported).
+# Digital transfers and monitoring can be done as well if you have
+# the digital daughterboard (see the section on using the S/PDIF port
+# for more information).
+#
+# Support for the Turtle Beach MultiSound Hurricane architecture is
+# composed of the following modules (these can also operate compiled
+# into the kernel):
+#
+# snd-msnd-lib - MultiSound base (requires snd)
+#
+# snd-msnd-classic - Base audio/mixer support for Classic, Monetery and
+# Tahiti cards
+#
+# snd-msnd-pinnacle - Base audio/mixer support for Pinnacle and Fiji cards
+#
+#
+# Important Notes - Read Before Using
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# The firmware files are not included (may change in future). You
+# must obtain these images from Turtle Beach (they are included in
+# the MultiSound Development Kits), and place them in /etc/sound for
+# example, and give the full paths in the Linux configuration. If
+# you are compiling in support for the MultiSound driver rather than
+# using it as a module, these firmware files must be accessible
+# during kernel compilation.
+#
+# Please note these files must be binary files, not assembler. See
+# the section later in this document for instructions to obtain these
+# files.
+#
+#
+# Configuring Card Resources
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# ** This section is very important, as your card may not work at all
+# or your machine may crash if you do not do this correctly. **
+#
+# * Classic/Monterey/Tahiti
+#
+# These cards are configured through the driver snd-msnd-classic. You must
+# know the io port, then the driver will select the irq and memory resources
+# on the card. It is up to you to know if these are free locations or now,
+# a conflict can lock the machine up.
+#
+# * Pinnacle/Fiji
+#
+# The Pinnacle and Fiji cards have an extra config port, either
+# 0x250, 0x260 or 0x270. This port can be disabled to have the card
+# configured strictly through PnP, however you lose the ability to
+# access the IDE controller and joystick devices on this card when
+# using PnP. The included pinnaclecfg program in this shell archive
+# can be used to configure the card in non-PnP mode, and in PnP mode
+# you can use isapnptools. These are described briefly here.
+#
+# pinnaclecfg is not required; you can use the snd-msnd-pinnacle module
+# to fully configure the card as well. However, pinnaclecfg can be
+# used to change the resource values of a particular device after the
+# snd-msnd-pinnacle module has been loaded. If you are compiling the
+# driver into the kernel, you must set these values during compile
+# time, however other peripheral resource values can be changed with
+# the pinnaclecfg program after the kernel is loaded.
+#
+#
+# *** PnP mode
+#
+# Use pnpdump to obtain a sample configuration if you can; I was able
+# to obtain one with the command `pnpdump 1 0x203' -- this may vary
+# for you (running pnpdump by itself did not work for me). Then,
+# edit this file and use isapnp to uncomment and set the card values.
+# Use these values when inserting the snd-msnd-pinnacle module. Using
+# this method, you can set the resources for the DSP and the Kurzweil
+# synth (Pinnacle). Since Linux does not directly support PnP
+# devices, you may have difficulty when using the card in PnP mode
+# when it the driver is compiled into the kernel. Using non-PnP mode
+# is preferable in this case.
+#
+# Here is an example mypinnacle.conf for isapnp that sets the card to
+# io base 0x210, irq 5 and mem 0xd8000, and also sets the Kurzweil
+# synth to 0x330 and irq 9 (may need editing for your system):
+#
+# (READPORT 0x0203)
+# (CSN 2)
+# (IDENTIFY *)
+#
+# # DSP
+# (CONFIGURE BVJ0440/-1 (LD 0
+# (INT 0 (IRQ 5 (MODE +E))) (IO 0 (BASE 0x0210)) (MEM 0 (BASE 0x0d8000))
+# (ACT Y)))
+#
+# # Kurzweil Synth (Pinnacle Only)
+# (CONFIGURE BVJ0440/-1 (LD 1
+# (IO 0 (BASE 0x0330)) (INT 0 (IRQ 9 (MODE +E)))
+# (ACT Y)))
+#
+# (WAITFORKEY)
+#
+#
+# *** Non-PnP mode
+#
+# The second way is by running the card in non-PnP mode. This
+# actually has some advantages in that you can access some other
+# devices on the card, such as the joystick and IDE controller. To
+# configure the card, unpack this shell archive and build the
+# pinnaclecfg program. Using this program, you can assign the
+# resource values to the card's devices, or disable the devices. As
+# an alternative to using pinnaclecfg, you can specify many of the
+# configuration values when loading the snd-msnd-pinnacle module (or
+# during kernel configuration when compiling the driver into the
+# kernel).
+#
+# If you specify cfg=0x250 for the snd-msnd-pinnacle module, it
+# automatically configure the card to the given io, irq and memory
+# values using that config port (the config port is jumper selectable
+# on the card to 0x250, 0x260 or 0x270).
+#
+# See the `snd-msnd-pinnacle Additional Options' section below for more
+# information on these parameters (also, if you compile the driver
+# directly into the kernel, these extra parameters can be useful
+# here).
+#
+#
+# ** It is very easy to cause problems in your machine if you choose a
+# resource value which is incorrect. **
+#
+#
+# Examples
+# ~~~~~~~~
+#
+# * MultiSound Classic/Monterey/Tahiti:
+#
+# modprobe snd
+# insmod snd-msnd-lib
+# insmod snd-msnd-classic io=0x290 irq=7 mem=0xd0000
+#
+# * MultiSound Pinnacle in PnP mode:
+#
+# modprobe snd
+# insmod snd-msnd-lib
+# isapnp mypinnacle.conf
+# insmod snd-msnd-pinnacle io=0x210 irq=5 mem=0xd8000 <-- match mypinnacle.conf values
+#
+# * MultiSound Pinnacle in non-PnP mode (replace 0x250 with your configuration port,
+# one of 0x250, 0x260 or 0x270):
+#
+# modprobe snd
+# insmod snd-msnd-lib
+# insmod snd-msnd-pinnacle cfg=0x250 io=0x290 irq=5 mem=0xd0000
+#
+# * To use the MPU-compatible Kurzweil synth on the Pinnacle in PnP
+# mode, add the following (assumes you did `isapnp mypinnacle.conf'):
+#
+# insmod snd
+# insmod mpu401 io=0x330 irq=9 <-- match mypinnacle.conf values
+#
+# * To use the MPU-compatible Kurzweil synth on the Pinnacle in non-PnP
+# mode, add the following. Note how we first configure the peripheral's
+# resources, _then_ install a Linux driver for it:
+#
+# insmod snd
+# pinnaclecfg 0x250 mpu 0x330 9
+# insmod mpu401 io=0x330 irq=9
+#
+# -- OR you can use the following sequence without pinnaclecfg in non-PnP mode:
+#
+# modprobe snd
+# insmod snd-msnd-lib
+# insmod snd-msnd-pinnacle cfg=0x250 io=0x290 irq=5 mem=0xd0000 mpu_io=0x330 mpu_irq=9
+# insmod snd
+# insmod mpu401 io=0x330 irq=9
+#
+# * To setup the joystick port on the Pinnacle in non-PnP mode (though
+# you have to find the actual Linux joystick driver elsewhere), you
+# can use pinnaclecfg:
+#
+# pinnaclecfg 0x250 joystick 0x200
+#
+# -- OR you can configure this using snd-msnd-pinnacle with the following:
+#
+# modprobe snd
+# insmod snd-msnd-lib
+# insmod snd-msnd-pinnacle cfg=0x250 io=0x290 irq=5 mem=0xd0000 joystick_io=0x200
+#
+#
+# snd-msnd-classic, snd-msnd-pinnacle Required Options
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# If the following options are not given, the module will not load.
+# Examine the kernel message log for informative error messages.
+# WARNING--probing isn't supported so try to make sure you have the
+# correct shared memory area, otherwise you may experience problems.
+#
+# io I/O base of DSP, e.g. io=0x210
+# irq IRQ number, e.g. irq=5
+# mem Shared memory area, e.g. mem=0xd8000
+#
+#
+# snd-msnd-classic, snd-msnd-pinnacle Additional Options
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# fifosize The digital audio FIFOs, in kilobytes. If not
+# specified, the default will be used. Increasing
+# this value will reduce the chance of a FIFO
+# underflow at the expense of increasing overall
+# latency. For example, fifosize=512 will
+# allocate 512kB read and write FIFOs (1MB total).
+# While this may reduce dropouts, a heavy machine
+# load will undoubtedly starve the FIFO of data
+# and you will eventually get dropouts. One
+# option is to alter the scheduling priority of
+# the playback process, using `nice' or some form
+# of POSIX soft real-time scheduling.
+#
+# calibrate_signal Setting this to one calibrates the ADCs to the
+# signal, zero calibrates to the card (defaults
+# to zero).
+#
+#
+# snd-msnd-pinnacle Additional Options
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# digital Specify digital=1 to enable the S/PDIF input
+# if you have the digital daughterboard
+# adapter. This will enable access to the
+# DIGITAL1 input for the soundcard in the mixer.
+# Some mixer programs might have trouble setting
+# the DIGITAL1 source as an input. If you have
+# trouble, you can try the setdigital.c program
+# at the bottom of this document.
+#
+# cfg Non-PnP configuration port for the Pinnacle
+# and Fiji (typically 0x250, 0x260 or 0x270,
+# depending on the jumper configuration). If
+# this option is omitted, then it is assumed
+# that the card is in PnP mode, and that the
+# specified DSP resource values are already
+# configured with PnP (i.e. it won't attempt to
+# do any sort of configuration).
+#
+# When the Pinnacle is in non-PnP mode, you can use the following
+# options to configure particular devices. If a full specification
+# for a device is not given, then the device is not configured. Note
+# that you still must use a Linux driver for any of these devices
+# once their resources are setup (such as the Linux joystick driver,
+# or the MPU401 driver from OSS for the Kurzweil synth).
+#
+# mpu_io I/O port of MPU (on-board Kurzweil synth)
+# mpu_irq IRQ of MPU (on-board Kurzweil synth)
+# ide_io0 First I/O port of IDE controller
+# ide_io1 Second I/O port of IDE controller
+# ide_irq IRQ IDE controller
+# joystick_io I/O port of joystick
+#
+#
+# Obtaining and Creating Firmware Files
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# For the Classic/Tahiti/Monterey
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# Download to /tmp and unzip the following file from Turtle Beach:
+#
+# ftp://ftp.voyetra.com/pub/tbs/msndcl/msndvkit.zip
+#
+# When unzipped, unzip the file named MsndFiles.zip. Then copy the
+# following firmware files to /etc/sound (note the file renaming):
+#
+# cp DSPCODE/MSNDINIT.BIN /etc/sound/msndinit.bin
+# cp DSPCODE/MSNDPERM.REB /etc/sound/msndperm.bin
+#
+# When configuring the Linux kernel, specify /etc/sound/msndinit.bin and
+# /etc/sound/msndperm.bin for the two firmware files (Linux kernel
+# versions older than 2.2 do not ask for firmware paths, and are
+# hardcoded to /etc/sound).
+#
+# If you are compiling the driver into the kernel, these files must
+# be accessible during compilation, but will not be needed later.
+# The files must remain, however, if the driver is used as a module.
+#
+#
+# For the Pinnacle/Fiji
+# ~~~~~~~~~~~~~~~~~~~~~
+#
+# Download to /tmp and unzip the following file from Turtle Beach (be
+# sure to use the entire URL; some have had trouble navigating to the
+# URL):
+#
+# ftp://ftp.voyetra.com/pub/tbs/pinn/pnddk100.zip
+#
+# Unpack this shell archive, and run make in the created directory
+# (you need a C compiler and flex to build the utilities). This
+# should give you the executables conv, pinnaclecfg and setdigital.
+# conv is only used temporarily here to create the firmware files,
+# while pinnaclecfg is used to configure the Pinnacle or Fiji card in
+# non-PnP mode, and setdigital can be used to set the S/PDIF input on
+# the mixer (pinnaclecfg and setdigital should be copied to a
+# convenient place, possibly run during system initialization).
+#
+# To generating the firmware files with the `conv' program, we create
+# the binary firmware files by doing the following conversion
+# (assuming the archive unpacked into a directory named PINNDDK):
+#
+# ./conv < PINNDDK/dspcode/pndspini.asm > /etc/sound/pndspini.bin
+# ./conv < PINNDDK/dspcode/pndsperm.asm > /etc/sound/pndsperm.bin
+#
+# The conv (and conv.l) program is not needed after conversion and can
+# be safely deleted. Then, when configuring the Linux kernel, specify
+# /etc/sound/pndspini.bin and /etc/sound/pndsperm.bin for the two
+# firmware files (Linux kernel versions older than 2.2 do not ask for
+# firmware paths, and are hardcoded to /etc/sound).
+#
+# If you are compiling the driver into the kernel, these files must
+# be accessible during compilation, but will not be needed later.
+# The files must remain, however, if the driver is used as a module.
+#
+#
+# Using Digital I/O with the S/PDIF Port
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# If you have a Pinnacle or Fiji with the digital daughterboard and
+# want to set it as the input source, you can use this program if you
+# have trouble trying to do it with a mixer program (be sure to
+# insert the module with the digital=1 option, or say Y to the option
+# during compiled-in kernel operation). Upon selection of the S/PDIF
+# port, you should be able monitor and record from it.
+#
+# There is something to note about using the S/PDIF port. Digital
+# timing is taken from the digital signal, so if a signal is not
+# connected to the port and it is selected as recording input, you
+# will find PCM playback to be distorted in playback rate. Also,
+# attempting to record at a sampling rate other than the DAT rate may
+# be problematic (i.e. trying to record at 8000Hz when the DAT signal
+# is 44100Hz). If you have a problem with this, set the recording
+# input to analog if you need to record at a rate other than that of
+# the DAT rate.
+#

+===========================================
+Sound Blaster Live mixer / default DSP code
+===========================================
+
+
+The EMU10K1 chips have a DSP part which can be programmed to support
+various ways of sample processing, which is described here.
+(This article does not deal with the overall functionality of the
+EMU10K1 chips. See the manuals section for further details.)
+
+The ALSA driver programs this portion of chip by default code
+(can be altered later) which offers the following functionality:
+
+
+IEC958 (S/PDIF) raw PCM
+=======================
+
+This PCM device (it's the 4th PCM device (index 3!) and first subdevice
+(index 0) for a given card) allows to forward 48kHz, stereo, 16-bit
+little endian streams without any modifications to the digital output
+(coaxial or optical). The universal interface allows the creation of up
+to 8 raw PCM devices operating at 48kHz, 16-bit little endian. It would
+be easy to add support for multichannel devices to the current code,
+but the conversion routines exist only for stereo (2-channel streams)
+at the time.
+
+Look to tram_poke routines in lowlevel/emu10k1/emufx.c for more details.
+
+
+Digital mixer controls
+======================
+
+These controls are built using the DSP instructions. They offer extended
+functionality. Only the default build-in code in the ALSA driver is described
+here. Note that the controls work as attenuators: the maximum value is the
+neutral position leaving the signal unchanged. Note that if the same destination
+is mentioned in multiple controls, the signal is accumulated and can be wrapped
+(set to maximal or minimal value without checking of overflow).
+
+
+Explanation of used abbreviations:
+
+DAC
+ digital to analog converter
+ADC
+ analog to digital converter
+I2S
+ one-way three wire serial bus for digital sound by Philips Semiconductors
+ (this standard is used for connecting standalone DAC and ADC converters)
+LFE
+ low frequency effects (subwoofer signal)
+AC97
+ a chip containing an analog mixer, DAC and ADC converters
+IEC958
+ S/PDIF
+FX-bus
+ the EMU10K1 chip has an effect bus containing 16 accumulators.
+ Each of the synthesizer voices can feed its output to these accumulators
+ and the DSP microcontroller can operate with the resulting sum.
+
+
+``name='Wave Playback Volume',index=0``
+---------------------------------------
+This control is used to attenuate samples for left and right PCM FX-bus
+accumulators. ALSA uses accumulators 0 and 1 for left and right PCM samples.
+The result samples are forwarded to the front DAC PCM slots of the AC97 codec.
+
+``name='Wave Surround Playback Volume',index=0``
+------------------------------------------------
+This control is used to attenuate samples for left and right PCM FX-bus
+accumulators. ALSA uses accumulators 0 and 1 for left and right PCM samples.
+The result samples are forwarded to the rear I2S DACs. These DACs operates
+separately (they are not inside the AC97 codec).
+
+``name='Wave Center Playback Volume',index=0``
+----------------------------------------------
+This control is used to attenuate samples for left and right PCM FX-bus
+accumulators. ALSA uses accumulators 0 and 1 for left and right PCM samples.

+the ??rear?? right DAC PCM slot of the AC97 codec.
+
+``name='Wave LFE Playback Volume',index=0``
+-------------------------------------------
+This control is used to attenuate samples for left and right PCM FX-bus

+and center / LFE outputs are affected.
+
+``name='Tone Control - Bass',index=0``
+--------------------------------------
+This control sets the bass intensity. There is no neutral value!!

+===========================
+
+``name='EMU10K1 PCM Volume',index 0-31``
+----------------------------------------
+Channel volume attenuation in range 0-0xffff. The maximum value (no

+* 2 - right, default 0xffff (no attenuation)
+
+``name='EMU10K1 PCM Send Routing',index 0-31``
+----------------------------------------------
+This control specifies the destination - FX-bus accumulators. There are
+twelve values with this mapping:
+
+* 0 - mono, A destination (FX-bus 0-15), default 0
+* 1 - mono, B destination (FX-bus 0-15), default 1
+* 2 - mono, C destination (FX-bus 0-15), default 2
+* 3 - mono, D destination (FX-bus 0-15), default 3
+* 4 - left, A destination (FX-bus 0-15), default 0
+* 5 - left, B destination (FX-bus 0-15), default 1
+* 6 - left, C destination (FX-bus 0-15), default 2

+* 8 - right, A destination (FX-bus 0-15), default 0
+* 9 - right, B destination (FX-bus 0-15), default 1
+* 10 - right, C destination (FX-bus 0-15), default 2
+* 11 - right, D destination (FX-bus 0-15), default 3
+
+Don't forget that it's illegal to assign a channel to the same FX-bus accumulator
+more than once (it means 0=0 && 1=0 is an invalid combination).
+
+``name='EMU10K1 PCM Send Volume',index 0-31``
+---------------------------------------------
+It specifies the attenuation (amount) for given destination in range 0-255.
+The channel mapping is following:
+
+* 0 - mono, A destination attn, default 255 (no attenuation)
+* 1 - mono, B destination attn, default 255 (no attenuation)
+* 2 - mono, C destination attn, default 0 (mute)
+* 3 - mono, D destination attn, default 0 (mute)
+* 4 - left, A destination attn, default 255 (no attenuation)
+* 5 - left, B destination attn, default 0 (mute)
+* 6 - left, C destination attn, default 0 (mute)
+* 7 - left, D destination attn, default 0 (mute)
+* 8 - right, A destination attn, default 0 (mute)
+* 9 - right, B destination attn, default 255 (no attenuation)

+===================================
+Serial UART 16450/16550 MIDI driver
+===================================
+
+The adaptor module parameter allows you to select either:
+
+* 0 - Roland Soundcanvas support (default)
+* 1 - Midiator MS-124T support (1)
+* 2 - Midiator MS-124W S/A mode (2)
+* 3 - MS-124W M/B mode support (3)
+* 4 - Generic device with multiple input support (4)
+
+For the Midiator MS-124W, you must set the physical M-S and A-B
+switches on the Midiator to match the driver mode you select.
+
+In Roland Soundcanvas mode, multiple ALSA raw MIDI substreams are supported
+(midiCnD0-midiCnD15). Whenever you write to a different substream, the driver
+sends the nonstandard MIDI command sequence F5 NN, where NN is the substream
+number plus 1. Roland modules use this command to switch between different
+"parts", so this feature lets you treat each part as a distinct raw MIDI
+substream. The driver provides no way to send F5 00 (no selection) or to not
+send the F5 NN command sequence at all; perhaps it ought to.
+
+Usage example for simple serial converter:
+::
+
+ /sbin/setserial /dev/ttyS0 uart none
+ /sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 speed=115200
+
+Usage example for Roland SoundCanvas with 4 MIDI ports:
+::
+
+ /sbin/setserial /dev/ttyS0 uart none
+ /sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 outs=4
+
+In MS-124T mode, one raw MIDI substream is supported (midiCnD0); the outs
+module parameter is automatically set to 1. The driver sends the same data to
+all four MIDI Out connectors. Set the A-B switch and the speed module
+parameter to match (A=19200, B=9600).
+
+Usage example for MS-124T, with A-B switch in A position:
+::
+
+ /sbin/setserial /dev/ttyS0 uart none
+ /sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=1 \
+ speed=19200
+
+In MS-124W S/A mode, one raw MIDI substream is supported (midiCnD0);
+the outs module parameter is automatically set to 1. The driver sends
+the same data to all four MIDI Out connectors at full MIDI speed.
+
+Usage example for S/A mode:
+::
+
+ /sbin/setserial /dev/ttyS0 uart none
+ /sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=2
+
+In MS-124W M/B mode, the driver supports 16 ALSA raw MIDI substreams;
+the outs module parameter is automatically set to 16. The substream
+number gives a bitmask of which MIDI Out connectors the data should be
+sent to, with midiCnD1 sending to Out 1, midiCnD2 to Out 2, midiCnD4 to
+Out 3, and midiCnD8 to Out 4. Thus midiCnD15 sends the data to all 4 ports.
+As a special case, midiCnD0 also sends to all ports, since it is not useful
+to send the data to no ports. M/B mode has extra overhead to select the MIDI
+Out for each byte, so the aggregate data rate across all four MIDI Outs is
+at most one byte every 520 us, as compared with the full MIDI data rate of
+one byte every 320 us per port.
+
+Usage example for M/B mode:
+::
+
+ /sbin/setserial /dev/ttyS0 uart none
+ /sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=3
+
+The MS-124W hardware's M/A mode is currently not supported. This mode allows
+the MIDI Outs to act independently at double the aggregate throughput of M/B,
+but does not allow sending the same byte simultaneously to multiple MIDI Outs.
+The M/A protocol requires the driver to twiddle the modem control lines under
+timing constraints, so it would be a bit more complicated to implement than
+the other modes.
+
+Midiator models other than MS-124W and MS-124T are currently not supported.
+Note that the suffix letter is significant; the MS-124 and MS-124B are not
+compatible, nor are the other known models MS-101, MS-101B, MS-103, and MS-114.
+I do have documentation (tim.mann@compaq.com) that partially covers these models,
+but no units to experiment with. The MS-124W support is tested with a real unit.
+The MS-124T support is untested, but should work.
+
+The Generic driver supports multiple input and output substreams over a single
+serial port. Similar to Roland Soundcanvas mode, F5 NN is used to select the
+appropriate input or output stream (depending on the data direction).
+Additionally, the CTS signal is used to regulate the data flow. The number of
+inputs is specified by the ins parameter.
