I'm not sure Wine should enumerate these.  How can it tell the difference
so as to announce the correct channel mapping to applications?
E.g. 41 vs 50, both 5 channels? Ideally, that should be announced as
one device (as it really is), capable of supporting different formats,
with one preferred format (perhaps the one with most channels) that GetMixFormat uses.

OTOH, I find it important that Wine announces a device capable of more
than stereo if there's one in the system.
