--- Comment #106 from Michael Cronenworth mike@cchtml.com 2011-12-20 21:06:04 CST --- After 24 hours and trying patch set 5 I have more results. Set 5 is about the same as set 4. Sound works properly about half of the time, but it is better than without the patches. There are times, usually under load so the buffers are probably underrun, that I hear "fuzz". Sometimes the fuzz is only for a few seconds, but most of the time the fuzz is constant once it starts. I have to quit the application and restart PA for Wine to sound proper again (restarting Wine is not enough). Non-wine apps sound fine even when Wine is distorted though. I see this message spammed to my terminal when the fuzz occurs:
ALSA lib pcm.c:7316:(snd_pcm_recover) underrun occurred
