Shouldn't that be defined in a more generic way? As far as I know,
there's no way to tell what the difference between "Mic1,Mic2" and
"Mic1+Mic2" would be from the userspace.

I guess the larger issue is that you'd need to have controls that are
common to both channels (ie that would change the routing of both
mixers), but aren't sharing the same controls structure since the
label would be different.
