Greetings Huw,
Been following your winealsa work and I'm pretty hyped about this commit - mmdev is finally alsa-free \o/
Have you considered splitting the props handling - get_device_path, get_physical_speakers? AFAICT this should reduce the duplication on the unix side (alsa vs pulse vs others). More importantly it makes it easier to avoid the caller allocated string, by passing the vendor/device/other data directly.
What are your thoughts on having a single mmdev.drv, which calls into winealsa.drv/winepulse.drv/other? Are wineandroid/mmdev, winecoreaudio and wineoss in scope in the mid/long run?
Thanks in advance, Emil

We could split these, but I didn't want the number of syscalls to escalate. If there really are only two properties then that doesn't sound too bad.

Yes, long term the aim would be to have a single PE-side. I've been keeping the unixlib interfaces as close as possible to facilitate this. Once all of the drivers are done, we'll had a good idea of what that'll look like.
winecoreaudio is already done and I've started on wineoss, though I still have the midi bits of winealsa to upstream.
Until you'd mentioned it, I'd forgotten about sound side of wineandroid, so I guess that's one more to do :-(
Huw.

Are there any technical implications of having say 10 vs 20 syscalls or is it mostly to preserve one's sanity? The syscall lookup machinery should not care, unless we're talking about orders of magnitude.

Very nice.
Speaking of midi bits: Which version of Windows deprecates(?) winmm.dll and/or the multimedia extensions MME?

^W^W^W^W^W I didn't say anything :-P
Keep up the good work. -Emil

No technical reasons, just trying to keep the api sane.

It does beg the question of whether wineandroid is still useful for people.
Huw.

Sadly it's mostly bitrotting at this point. Unless someone wants to work on bringing it up to date with latest Android, it's not worth spending a lot of effort on it.
