sound stopped working

[joerg]

Sound worked for a few hours (less than a day) after the upgrade to ubuntu hardy, then suddenly stopped completly. The strange thing is, that I am not aware, that I changed anything around that time.

I watched a small movie from my camcorder with totem (sound was OK), stopped watching and wanted to watch the same movie with vlc, but sound failed since that moment - no idea what the cause might be. It never worked again since that. The problem persists reboots.

I just rebooted with an old knoppix cd to make sure, that this computer still could do audio output: it worked out of the box (alsa, but not pulseaudio).

any more infos I could give?
