- * The user of a channel mask needs to know the context of whether it is for output or input.
- * The constants AUDIO_CHANNEL_OUT_* or AUDIO_CHANNEL_IN_* apply to the bits portion.
- * It is not permitted for no bits to be set.

- * AUDIO_CHANNEL_REPRESENTATION_INDEX

- *
- * Warning: current representation distinguishes between input and output, but this will not the be
