[Bug 21873] New: Wine corrupts sound when using alsa's dmix

http://bugs.winehq.org/show_bug.cgi?id=21873

Summary: Wine corrupts sound when using alsa's dmix
           Product: Wine
           Version: 1.1.39
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When dmix is enabled, alsa corrupts the sound output (even for other
applications). When launching Wine, there are 2 lines related to this in the
console log :

ALSA lib pcm_dmix.c:949:(snd_pcm_dmix_open) The dmix plugin supports only
playback stream
ALSA lib pcm.c:7236:(snd_pcm_recover) underrun occured

Are you using pulseaudio?

I don't see anything about Wine there. Does using native Linux programs with
alsa and dmix work fine?

What distro? Have you compiled kernel yourself? If so, did you enable old API
compatibility for ALSA?

Sorry I forgot to add that launching Wine triggers the corruption.

I'm using Gentoo, kernel compiled by myself, I'm not using the kernel's version
of ALSA but the Portage's one.

What is supposed to happen if the old API compatibility isn't activated? 'Cause
the sound works with Wine, it's just corrupted/cracky (and corrupts it for any
other app). I then have to mute/unmute the master channel to have a normal
sound again.

Also note that Wine corrupts the sound when it starts, but if I mute/unmute the
master channel without closing Wine, even the sound from Wine's apps works
well.

Report to kernel/Gentoo. Not a Wine bug.

because you have to use type asym for playback using dmix and capture using
dsnoop
