I'll add a 'me too' to this one. However for me even a reboot has stopped curing it. I now have no sound in KDE, but skype and mplayer etc all still work.

I also have a USB sound card. If that is connected to the computer on boot up, KDE doesn't find it. If I connect it after booting up, KDE finds it and I can use it. So I suspect this problem is some kind of initialisation thing where KDE is searching for the sound card before it is 'ready'.
