             Bug #: 29768
           Summary: Constant xruns in alsa
           Product: Wine
           Version: 1.4-rc1
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org

    Classification: Unclassified
   Regression SHA1: f6890ef0e227afd12ce2325497d0cae478602c7d


Before 1.3.28 I could play dssi-vst (VST plugin adapter for Linux) and
Synthesia (piano game for windows, similar to Guitar Hero) simultaneously with
no xruns

    winmm: Determine the driver from MMDevAPI.

    This uses a half-implemented, Wine-specific IMMDevice object to extract
    the driver name.

After this commit dssi-vst works with no problems. But once Synthesia starts
console output looks like this:
alsa_pcm: xrun of at least 0.046 msecs
alsa_pcm: xrun of at least 0.021 msecs
...
About hundred such messages in 3 seconds and then jackd kills dssi-vst.

P.S. I'm using alsa only. No pulse audio.
