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