[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:
