[Bug 29768] New: Constant xruns in alsa

http://bugs.winehq.org/show_bug.cgi?id=29768

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: [e-mail]
        ReportedBy: [e-mail]
                CC: [e-mail]
    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.

Thanks for reporting.

Can you attach a log with the channels from http://wiki.winehq.org/Sound?

Also, which MIDI synthesizer are you using (timidity, fluidsynth...?)

Just to be clear, the problem you're reporting is underruns in Synthesia,
correct? dssi-vst is working fine?

Created attachment 38668

synthesia debug backtrace

How it all works:
1. I start jackd (used by dssi-vst)
jackd --realtime -Z -t 3000 --driver alsa --device "hw:Live" -p 512 -r 96000 &
2. Start dssi-vst with vst (MIDI synthesizer)
vsthost $HOME/.wine-music/drive_c/Program\ Files/Art\ Vista/Virtual\ Grand\
Piano/VSTPlugins/Virtual\ Grand\ PianoVST.dll
3. In VST GUI I load preset.
4. Start Synthesia.
5. In Synthesia options it's possible to select midi output. There is loaded
VST in the list.
6. After regression. Once Synthesia starts, there is flood of xrun warnings in
console. In a few seconds flood stops with:
**** alsa_pcm: xrun of at least 0.039 msecs
jackd watchdog: timeout - killing jackd
ERROR: Remote VST plugin communication failure in GUI thread
ERROR: Remote VST plugin communication failure in audio thread
Remote VST plugin audio thread: returning

7. dssi-vst killed. Synthesia works, but no sound on VST midi port (other ports
work).

dssi-vst uses wine, but doesn't react to WINEDEBUG. Attached Synthesia output
with debug channels.

This is your friendly reminder that there has been no bug activity for 2 years.
Is this still an issue in current (1.7.16 or newer) wine?
