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.
