I use Ubuntu, and not Kubuntu.  As far as I know, with the latest BIOS
version the volume keys act as regular keyboard keys in Ubuntu.  However
the software doesn't know which mixer channel to control when it gets
the key events (there's no "Master" channel that's the default, so GNOME
falls back to "Mic").  With Ubuntu you can fix that by going to System
-> Preferences -> Sound and choosing "PCM" as the mixer channel to
control.  I don't know how to do that in Kubuntu.
