Sound just stopped working (Ubuntu 10.10)


After 2-3 months of working fine. I have a win7 box hooked thru a KVM switch to the same speakers and they work from there. I booted up a live CD (Mint Linux 10) on the non-working machine, and the speakers work fine.

I checked and I have rights to "Use audio devices".

I ran the following and got:

I guess the last one is supposed to play something, but I heard NOTHING. I've also lost the "Volume icon" in the top panel (Gnome).

This is extremely frustrating as it is a RE-install of a previous version of Ubuntu 10.10. However, things have been working fine for a couple of months.

Anyone have any ideas on how to get my sound back?
