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