--- Comment #46 from Hogne Håskjold haskjold@gmail.com 2012-03-18 09:08:17 CDT --- Some follow up info:
The messages going to the console when getting distorted sound: ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred ... err:ole:CoInitializeEx Attempt to change threading model of this apartment from multi-threaded to apartment threaded
Not sure if that last one is related to sound though.
"pulseaudio -k" to restart pulseaudio will make sound work for a while in wine again without distortion, but not always.
