| 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. | |
