kde 3.3.0: All sound settings at 0 on SuSE 9.1

Hi there, I'm running KDE 3.3.0 on 3 machines now - 1 SuSE 9.0 and 2 SuSE 9.1. I've got the same problem on both 9.1-machines: KDE is setting all sound-options to 0. Everytime I log in I have to do all sound settings again. I tried to do the settings in YAST - so success. I tried different mixers - no success. It must be a KDE 3.3.0 problem because it exists since installing 3.3.0. But only on SuSE 9.1. 9.0 is running well. Anyone an idea to solve the problem? Greetings Jochen
