More bits in the channel mask than the number of channels is used to mark an
unfixed channel mask. audioconvert for example is then selecting a subset of
those bits during negotiation.
So this part at least seems wrong.


But you only want the inverse, right? Less bits in the channel mask than
channels read, and having all additional channels set to an undefined position?
That change would seem possible, but I think it will need changes in
audioconvert to handle that properly first.
