Package: libwine-alsa-unstable
Version: 1.5.6-2
Severity: normal

Dear Maintainer,
when trying to record sound (e.g. using arecord) played by some application running on WINE (e.g. vlc.exe) via ALSA, and if the recording application is launched *before* the playback application, recording stops immediately when playback starts, and after a while ALSA reports an "Input/output error". This does not happen with native playback applications, e.g. the Linux version of vlc.
Funny enough, if recordings starts *after* playback has begun, everything works fine. 

How to reporduce:

1. In a terminal, issue

  sudo alsactl restore; arecord -D default -f dat -v -V stereo test.wav

2. In another terminal, launch vlc.exe by issuing something like

  WINEPREFIX=/path/to/prefix wine /path/to/vlc.exe /path/to/some/audiofile

3. Wait for a few seconds... and see arecord complaining:

  arecord: pcm_read:1801: read error: Input/output error

4. Re-launch arecrod:

  sudo alsactl restore; arecord -D default -f dat -v -V stereo test.wav

5. Watch arecord recording happily ever after.
I initially suspected WINE to somehow force access to my soundcard's capture device (A SB Live, which seems not to be dsnoop'd by default), but after creating a dsnoop'd device (which did allow for multiple simultaneous recordings with arecord when playing back audio with Linux's vlc) and teaching WINE to actually use it, the problem unfortunately remained. 

Best regards --

	Torsten

The pulseaudio driver is now merged into wine, so this should work
correctly now if you use pulseaudio and parecord instead of alsa and
arecord.

Best wishes,
