Since upgrading my Natty install to Gnome 3, I've been having occasional issues with sound. Most of the time, sound works fine, but here and there it will be really staticy.
One cause I've noticed is when the cpu is heavily tasked, this will cause sound to get staticy. Sound then remains staticy and garbled even after tasks finish and cpu usage drops to normal. Forcing Pulseaudio to restart (with "killall pulseaudio") seems to fix the issue for that instance.
The more annoying cause of staticy audio has been running certain games. It happens 100% of the time when these games are running. Linux-native game Trine is really bad, with the sound issues making the game completely unenjoyable. Warcraft III running in Wine also does it, but to a lesser extent.
These games both ran perfectly before the upgrade to Gnome 3, and I'm confused as to why it would change anything. After searching a bit, the only (remotely) similar thread ( crackling audio with Pulseaudio ) I've found says that it could be "bad latency and incorrectly set frequency settings in Pulse Audio".
If it were something as simple as incorrect frequency settings in Pulseaudio, where would one go to change it?
Any help, input, or other assistance is greatly appreciated. Thanks.
