Bug Description
I used Kubuntu Jaunty 64. This weekend I lost sound because of unknown reason. I didn't change anything. I was frustrated and upgraded to the development release Karmic. It at least gives me an error message about the lack of sound. The sound works correctly in Windows.
Hardware:
Intel MB with Intel HDA STAC92xx (from KDE System Settings - Multimedia)
Hooked to an amplifier with optical cable (S/PDIF)
Problem:
YouTube, Kaffeine, VLC eventually (like after 1min of usage) break the output. I get system notification that Phonon failed to use the digital output and fell back to the analog. After that, I don't get any sounds from applications and system. Suprisingly Amarok still plays music, even after I restart it after the breakage...

I have some new information about this. I just watched an entire 2h movie with VLC player. Worked nicely, fed DTS to my amplifier the whole time. And sounds even work afterwards.
After, I played YouTube video and got a system message ("blink") and boom! The sound was broken. It seems that simultaneous sounds tend to brake the audio. Some kind of race condition?
