^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) The Digital TV audio device controls the MPEG2 audio decoder of the Digital
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) types and and ioctl definitions can be accessed by including
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) ``linux/dvb/audio.h`` in your application.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) Please note that some Digital TV cards don’t have their own MPEG decoder, which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) results in the omission of the audio and video device.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) These ioctls were also used by V4L2 to control MPEG decoders implemented
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) in V4L2. The use of these ioctls for that purpose has been made obsolete
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) and proper V4L2 ioctls or controls have been created to replace that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) functionality.
