Sound stopped working

[wfischer]

Yesterday, my sound worked fine. Last night, the power flickered in my house, but it happened so fast that it didn't seem to disturb much - I was watching a video on a different PC and the video didn't skip or anything. This morning I came into my office and found that my computer had rebooted itself. The volume was turned up all the way, and when I put on a song in Amarok, there was no sound. Kmix is now saying the only playback device is Dummy Output. Typing 'lspci -v' in a terminal shows NO audio devices. I went through the troubleshooting guide at https://help.ubuntu.com/community/SoundTroubleshooting and nothing there worked. I've tried removing and reinstalling alsa and pulseaudio, and I went into the BIOS and changed onboard audio from 'auto' to 'enabled'. Still, lspci -v shows no audio devices whatsoever. Did gremlins sneak into my PC overnight and steal the sound chip off my motherboard? Or, did that brief power flicker destroy my sound chip while leaving everything else seemingly untouched? Or, is there another explanation that I'm not aware of? Any help would be greatly appreciated; it's far too quiet in here!

Re: Sound stopped working

Hi...

Out of curiosity, do you get sound if you put in a live CD? Does this copy recognize the your chipset? Am I correct in assuming that you have no other OS (like Windows) installed on another partition?

Also, can you post the output of just "lspci" without the "-v" from your installed copy of Kubuntu? What is the brand and model of your system? Lots of questions, I know, but the details will help.

Thanks

Regards...
