Well, those people might not know that there are multiple drivers, or
might not care about drivers they don't use. Not everyone is as thorough
as we'd like them to be :)

As for these questions, I can answer them all at once. I am currently
re-implementing MMDevAPI to use a similar driver architecture to what
WinMM uses. (Yes, this is Alexandre-approved ;-) ) I am at the point
where a merge of my work into Wine is probably two or three weeks away.
After we are satisfied with the MMDevAPI implementation, we will have to
begin work on re-implementing WinMM and DSound on top of MMDevAPI, as
So the old, unmaintained WinMM drivers, as well as the current,
maintained WinMM drivers, will be replaced by a single MMDevAPI-based
implementation of WinMM. The maintenance burden will then be to keep the
MMDevAPI drivers up-to-date, which is really the same problem you're
asking about. But the hope is to make their first implementations
_good_, and then keep them all correct and current, without letting any
For the record, I am planning on having ALSA (complete-ish, ALSA sucks),
OSSv4 (complete), OSX CoreAudio (in progress), and PulseAudio (not yet
started) implementations from the start. I would also like a JACK
implementation for the pro-audio crowd (plus, I love JACK), but that's
In any case, the MMDevAPI drivers are much simpler and better organized
than the WinMM drivers. I expect maintaining them and writing tests for
them will be a much easier task than maintaining the WinMM drivers.
Your continued work on the WinMM family is appreciated. That will help
make the re-implementation on top of MMDevAPI higher quality from the start.
