-
- - Drivers can enumerate up to 32 video and audio inputs. This field

- was the currently selected video input. It is a bit mask. The LSB
- corresponds to audio input 0, the MSB to input 31. Any number of
- bits can be set, or none.
-
- When the driver does not enumerate audio inputs no bits must be
- set. Applications shall not interpret this as lack of audio
- support. Some drivers automatically select audio sources and do
- not enumerate them since there is no choice anyway.
