+Digital TV Audio Device
+#######################
+
+The Digital TV audio device controls the MPEG2 audio decoder of the Digital
+TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
+types and and ioctl definitions can be accessed by including
+``linux/dvb/audio.h`` in your application.
+
+Please note that some Digital TV cards don’t have their own MPEG decoder, which
+results in the omission of the audio and video device.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.
