[Bug 28221] New: Severe sound stutter in games using OpenAL

http://bugs.winehq.org/show_bug.cgi?id=28221

Summary: Severe sound stutter in games using OpenAL
           Product: Wine
           Version: 1.3.19
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winealsa.drv
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

At least some games using OpenAL (and probably also FMOD) have some severe
sound problems with Wine versions newer than 1.3.18. Wile cutscenes seem
unaffected the in game sound effects stutter a lot. I've tested this with both
Mafia 2 and Bioshock 2 but I wouldn't be surprised if more games using OpenAL
are affected. Sadly I have no way of testing if this is an ALSA-only problem or
if the same goes for OSS.

After doing a regression test this seems to be a result of the following
commit:

Prior to this commit the sound is fine.

I tested this against Bioshock 1 (which Google tells me uses OpenAL and/or
FMOD) and it worked fine. I'll try to find a copy of Bioshock 2, but in the
meantime can you give me the information requested at
http://wiki.winehq.org/Sound? Having DirectSound in Emulation mode is
preferred.

True, Bioshock 1 is not affected by this and neither is Mafia 1, but for some
reason both of their sequels are. As for Emulation vs Full Hardware
Acceleration there's no difference. Neither do I notice any difference when
tweaking the HelBuflen, SndQueueMax, SndQueueMin, MaxShadowSize,
DefaultSampleRate and DefaultBitsPerSample registry keys.

One thing that both applications seem to report from Wine 1.3.19 and onward is
however a bunch of the following message:

"fixme:alsa:AudioClient_GetMixFormat Don't know what to do with 6 channels,
pretending there's only 2 channels"

I don't know if that's somehow related to the stuttering but that's pretty much
the only difference in terminal output that I see between Wine 1.3.18 and
1.3.19, without adding any special debugging levels.

As for my systems specs I'm running a Gentoo system with a 32bit 3.0.1 kernel
using Alsa drivers ver. 1.0.24 built into the kernel. Installed OpenAL version
is 1.13.

The logs I've added above are the results from running both Mafia 2 and
Bioshock 2 with Wine 1.3.18 (working sound) and 1.3.19 (with stuttering) using
"WINEDEBUG=+tid,+mmdevapi,+winmm,+dsound,+oss,+alsa,+coreaudio". The logs only
cover entering the games main menus where the problem first occurs (moving the
mouse over the different menu options).

Problem solved, sort of anyway...

By looking at my own logs and your mmdevapi code I noticed that I kept getting
Xrun's when the stutter occurred, so I enlarged my Alsa buffer by editing my
.asoundrc file and now the stutter is gone.

No idea if you wanna make some kind of adjustment to your code, or if this is
even a Wine bug anymore, but at least now we know what caused the problem.
