It appears that CoreAudio does not support this yet. It is something that we
could actually use for our device(s) -- most of our channels have a number
of sources or psuedo sources that currently can only be controlled by our
console App. It would be cool to be able to export that control to CA
clients without having to resort to some set of private properties. So I
second Mike's motion -- it would be good to have source selectors on a per
channel (or at least per stream) basis.
