Occasionally some students manage to mangle their accounts
so that when they right click on the KMix icon and select Master Channel
the onboard audio isn't there ( only the HDMI one shows ). At the moment
we just do a wholesale delete of all the dot files and directories and that works
I was wondering if anyone know a slightly less sledgehammer technique.

Probably should have said it's currently
KDE 4.13.2
opensuse 13.1
but it has always had this problem since openSuse 12.2

This is due to changes in the Pulseaudio. If you open System Settings > Multimedia > Phonon > Audio Hardware Setup, then please ensure "Profile" is set to "Analog Stereo Duplex". In terms of resetting this administratively, please ensure the user is not logged in and delete ~/.pulse and ~/.config/pulse.

Groovy !

Many thanks
