It can be accessed through ``/dev/dvb/adapter?/audio?``. Data 18types and and ioctl definitions can be accessed by including 19``linux/dvb/audio.h`` in your application. 20 21Please note that some Digital TV cards don’t have their own MPEG decoder, which 22results in the omission of the audio and video device. 23 24These ioctls were also used by V4L2 to control MPEG decoders implemented 25in V4L2. The use of these ioctls for that purpose has been made obsolete 26and proper V4L2 ioctls or controls have been created to replace that 27functionality. 28 29 30.. toctree:: 31 :maxdepth: 1 32 33 audio_data_types 34 audio_function_calls 35
