The tests I did before were with alsa stack 1.0.25 over the in-kernel alsa
drivers 1.0.24 (had updated kernel recently). This time I am running over the
alsa drivers version 1.0.25 and sound is definitely better. I can't say there
is no crackling sound in any circumstance, but there surely isn't after
pulseaudio is freshly started or after killing pulseaudio, since it is directly
accessing alsa. At this point for me, sound in wine 1.4-rc4 works without
crackling just after starting pulseaudio and unlike before it can like that
indefinitely. If by any chance I begin to play a game after having started
pulseaudio for some time, I just have to restart pulseaudio. Anyway, the
likehood of having crackling audio is significantly smaller and when there is
crackling audio, sometimes it's in the background. The pulseaudio driver being
developed by Maarten shares the same results AFAIK.
Thank you and let's hope that with bug #28723 resolution and/or pulseaudio
developers addressing the bugs you reported, this situation can be finally
resolved in the future.
