I'll comment on that separately.

Indeed, it became more and more convoluted as I dug into native's
"exclusive mode disabled" and other exceptions to the rule.
And it's not even handling 5:1 cards correctly!
Luckily, I needn't add todo_wine on top of that...
For instance, winmm:wave.ok is so convoluted that
one cannot tell any more what it actually checks.
I'll think about a different approach with better expressiveness.
For now, I consider it's time to get more tests into git
and to gather results on test.winehq.org.

That is the correct behavior AFAICT: S_FALSE <=> set pwfx2
I've not yet submitted all of my patches about IsFormatSupported
but you're right, that's an easy patch away.  I forgot that one.
For sure 5:1 needs more testing and I have no such HW.  You have.

Ouch.  I thought "Wine has dlls/mmdevapi, so it should always load",
but test.winehq.org shows that Solaris doesn't appear to have mmdevapi. Why?
