+config SND_OSSEMUL

+	select SOUND_OSS_CORE
+	help
+	  This option enables the build of OSS emulation layer.
+
+config SND_MIXER_OSS
+	tristate "OSS Mixer API"
+	depends on SND_OSSEMUL
+	help
+	  To enable OSS mixer API emulation (/dev/mixer*), say Y here
+	  and read <file:Documentation/sound/designs/oss-emulation.rst>.
+
+	  Many programs still use the OSS API, so say Y.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-mixer-oss.
+
+config SND_PCM_OSS
+	tristate "OSS PCM (digital audio) API"
+	depends on SND_OSSEMUL
+	select SND_PCM
+	help
+	  To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y
+	  here and read <file:Documentation/sound/designs/oss-emulation.rst>.
+
+	  Many programs still use the OSS API, so say Y.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-pcm-oss.
+
+config SND_PCM_OSS_PLUGINS
+	bool "OSS PCM (digital audio) API - Include plugin system"
+	depends on SND_PCM_OSS
+        default y
+	help
+          If you disable this option, the ALSA's OSS PCM API will not
+          support conversion of channels, formats and rates. It will
+          behave like most of new OSS/Free drivers in 2.4/2.6 kernels.
+
+config SND_PCM_TIMER
+	bool "PCM timer interface" if EXPERT
+	default y
+	help
+	  If you disable this option, pcm timer will be unavailable, so
+	  those stubs that use pcm timer (e.g. dmix, dsnoop & co) may work
+	  incorrectlly.
+
+	  For some embedded devices, we may disable it to reduce memory
+	  footprint, about 20KB on x86_64 platform.
+
+config SND_HRTIMER
+	tristate "HR-timer backend support"
+	depends on HIGH_RES_TIMERS
+	select SND_TIMER
+	help
+	  Say Y here to enable HR-timer backend for ALSA timer.  ALSA uses
+	  the hrtimer as a precise timing source. The ALSA sequencer code
+	  also can use this timing source.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-hrtimer.
+
+config SND_DYNAMIC_MINORS
+	bool "Dynamic device file minor numbers"
+	help
+	  If you say Y here, the minor numbers of ALSA device files in
+	  /dev/snd/ are allocated dynamically.  This allows you to have
+	  more than 8 sound cards, but requires a dynamic device file
+	  system like udev.
+
+	  If you are unsure about this, say N here.
+
+config SND_MAX_CARDS
+	int "Max number of sound cards"
+	range 4 256
+	default 32
+	depends on SND_DYNAMIC_MINORS
+	help
+	  Specify the max number of sound cards that can be assigned
+	  on a single machine.
+
+config SND_SUPPORT_OLD_API
+	bool "Support old ALSA API"
+	default y
+	help
+	  Say Y here to support the obsolete ALSA PCM API (ver.0.9.0 rc3
+	  or older).
+
+config SND_PROC_FS
+        bool "Sound Proc FS Support" if EXPERT
+        depends on PROC_FS
+        default y
+        help
+          Say 'N' to disable Sound proc FS, which may reduce code size about
+          9KB on x86_64 platform.
+          If unsure say Y.
+
+config SND_VERBOSE_PROCFS
+	bool "Verbose procfs contents"
+	depends on SND_PROC_FS
+	default y
+	help
+	  Say Y here to include code for verbose procfs contents (provides
+          useful information to developers when a problem occurs).  On the
+          other side, it makes the ALSA subsystem larger.
+
+config SND_VERBOSE_PRINTK
+	bool "Verbose printk"
+	help
+	  Say Y here to enable verbose log messages.  These messages
+	  will help to identify source file and position containing
+	  printed messages.
+
+	  You don't need this unless you're debugging ALSA.
+
+config SND_DEBUG
+	bool "Debug"
+	help
+	  Say Y here to enable ALSA debug code.
+
+config SND_DEBUG_VERBOSE
+	bool "More verbose debug"
+	depends on SND_DEBUG
+	help
+	  Say Y here to enable extra-verbose debugging messages.
+	  
+	  Let me repeat: it enables EXTRA-VERBOSE DEBUGGING messages.
+	  So, say Y only if you are ready to be annoyed.
+
+config SND_PCM_XRUN_DEBUG
+	bool "Enable PCM ring buffer overrun/underrun debugging"
+	default n
+	depends on SND_DEBUG && SND_VERBOSE_PROCFS
+	help
+	  Say Y to enable the PCM ring buffer overrun/underrun debugging.
+	  It is usually not required, but if you have trouble with
+	  sound clicking when system is loaded, it may help to determine
+	  the process or driver which causes the scheduling gaps.
+
+config SND_VMASTER

+config SND_DMA_SGBUF
