I have a similar problem in Gutsy (not in Feisty) to Kevin. When I adjust the volume with the keyboard the volume adjustment is erratic (it might go up or down, turn off the left channel, etc). Sometime adjusting the volume with the applet is better but if I'm using Totem while adjusting it does weird things. I have an external usb sound card (Trends Audio UD-10) and I did some changes to get it to be recognized (I disabled my onboard sound card in the BIOS so the usb card is the first one).:

This is the same change I did in Feisty and everything worked. Any pointers/help would be appreciated.
