Sound FAQ

KDE mixer (Kmix)- usually accessed from the mixer button on the KDE desktop's volume control- does not always properly control the SPDIF (S/PDIF, Toslink) output. This is certainly true of the sound chip ALC889A. To control the SPDIF output you can use the command line, text-based alsamixer program, and watch the red laser switch on and off. Don't look straight into the output of the SPDIF optical port! Instead put a piece of paper behind it or reflect the light off your finger.

Once you've used alsamixer to get your sound setup right, you can use

alsactl store

This saves the settings and on Kubuntu they will be restored next time you reboot.
