That's a general remark for all your commits here, but you should have
more context in your commit logs, for example to define what is the
usual use case for these microphones, if the playback volume applies
to all mic at once, or just a fraction of them, etc.

This should probably go in a separate patch, it isn't directly related
to the rest of the patch.

Looks good otherwise, thanks!
