I think this was discussed before in regards to d3d. Except not in the sense 
of bugs but differences between how d3d behaves for Wine and for some 
applications. AKA workarounds for applications. In some way that can be 
considered bugs.

I'm not sure how much of that is going on with sound drivers. And there are 
might not be an easy way to find out.

I think in this particular case where it's clear what it is a bug (most 
other drivers do the right thing and in agreement with MSDN) then it might 
be time for "todo_windows".

  There agreement was that drivers have specific workarounds for specific 
programs.
