| 6 | DVB Audio Device |
| 7 | ################ |
| 8 | The DVB audio device controls the MPEG2 audio decoder of the DVB |
| 9 | hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data |
| 10 | types and and ioctl definitions can be accessed by including |
| 11 | ``linux/dvb/audio.h`` in your application. |
| 12 | |
| 13 | Please note that some DVB cards don’t have their own MPEG decoder, which |
| 14 | results in the omission of the audio and video device. |
| 15 | |
| 16 | These ioctls were also used by V4L2 to control MPEG decoders implemented |
| 17 | in V4L2. The use of these ioctls for that purpose has been made obsolete |
| 18 | and proper V4L2 ioctls or controls have been created to replace that |
| 19 | functionality. |
