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.
