Ok, I just built a new system and installed Kubuntu. I'm having some sound problems, but they are very strange.
First sound worked fine out of the box, played a DVD fine, flash video, fine. The only trouble I was having was some static/interference which I assume is from the onboard sound not being the best.
Later I went to play a flash video, and I got no sound, just some slight static (from the onboard sound?) Played a DVD - no sound Restarted, Kubuntu played its opening tune, I heard it, but STILL no DVD sound or flash video sound. Emptying recycle bin sound ok. I played an mp3 in Amarok, music plays fine.
So I figured I'd figure it out later and went to go do something else. Later in the day I opened a flash game, and THERE WAS SOUND. Weird. Opened a DVD, sound. Flash video, sound. Yay! It fixed itself!
Later on, I go to play another flash video (after not using anything with sound at all for a bit) and I don't get any sound again! Opened DVD, no sound. But I opened a song and I have sound in Amarok still. Opened the same song in VLC and there was no sound. Kubuntu still plays a sound when loading KDE and emptying the recycle bin.
It hasn't fixed itself since.
