Data 11types and ioctl definitions can be accessed by including 12``linux/dvb/audio.h`` in your application. 13 14Please note that some Digital TV cards don't have their own MPEG decoder, which 15results in the omission of the audio and video device. 16 17These ioctls were also used by V4L2 to control MPEG decoders implemented 18in V4L2. The use of these ioctls for that purpose has been made obsolete 19and proper V4L2 ioctls or controls have been created to replace that 20functionality. 21 22 23.. toctree:: 24 :maxdepth: 1 25 26 audio_data_types 27 audio_function_calls
