0009 The Digital TV audio device controls the MPEG2 audio decoder of the Digital
0010 TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
0011 types and ioctl definitions can be accessed by including
0012 ``linux/dvb/audio.h`` in your application.
0013
0014 Please note that some Digital TV cards don't have their own MPEG decoder, which
0015 results in the omission of the audio and video device.
0016
0017 These ioctls were also used by V4L2 to control MPEG decoders implemented
0018 in V4L2. The use of these ioctls for that purpose has been made obsolete
0019 and proper V4L2 ioctls or controls have been created to replace that
0020 functionality.
