[Bug 21585] New: Alsa: wine stops other alsa output

http://bugs.winehq.org/show_bug.cgi?id=21585

Summary: Alsa: wine stops other alsa output
           Product: Wine
           Version: 1.1.37
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When starting an application that uses sound, other Alsa clients stop
outputting.

Specifically, if I run mplayer in one terminal, and then try to run either Eve,
Ventrilo, or winecfg from another terminal, mplayer keeps progressing but stops
outputting sound.

I can run multiple mplayers concurrently and the sounds overlap.  I can also
run aplay of a random wav file at the same time, so it seems like Alsa is
properly dmixing.  mplayer is using alsa (AO: [alsa])

When I start the wine app, sound doesn't work for it either, until I close the
original application (mplayer) and restart the wine application.

For example, mplayer, then winecfg = total silence, the Test Sound button does
nothing.  If I run only winecfg, I can use the Test Sound button (and it
works).  The alsa detection seems to work fine all the time, and detects the
wave out device as dmix:0.

When the Test Sound button plays, this is in the console: 
ALSA lib pcm.c:7234:(snd_pcm_recover) underrun occured

This problem also occurs if I run two wine applications (Eve and Ventrilo at
the same time).

I see this in the console too, all the time:
fixme:mixer:ALSA_MixerInit No master control found on HDA ATI HDMI, disabling
mixer

2.6.32-gentoo-r2, x86_64
ATI, fglrx 10.1
wine 1.1.37
On-board audio (snd_hda_intel module)
No pulseaudio, esd, or anything like that.
Happens on a new .wine folder too (moved the old one to .wine-bak, etc).

Thanks.
