When I run wine, the sound played in games stutter and effects are played with delays.
Note that this happens with $ unset ALSA_CONFIG_PATH $ wine game.exe too. I.e. when wine uses ALSA (/dev/snd/*) directly. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Possibly due to the recent change of PCM core to check the buffer updating in a more strict manner.
I can't say whether this is a regression. It might be possible. I'm encountering the problems for several months already (post-11.2 vanillas and then factory to 11.3 kernels).
I don't know which messages are suppressed. The BDL workaround warning is shown only once, and the others are from PulseAudio.
Sorry for the confusion, the ratelimit messages are from PA. And follows the POLLOUT error.
# echo 4 > /proc/asound/card0/pcm0p/xrun_debug
If I do this, the sound is OK. The background music is played well. There is a problem when music is mixed with an audio effect. Then I hear a scramble rather than the effect while the music is still playing. But this is a separate issue, I guess. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This shouldn't be needed ideally, but ALSA driver in 2.6.34 kernel seems too strict for some environment. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
