KDE 3.2.1 + Sound ?

Hello, I've updated my SuSE 9.0 (KDE 3.1.4) to KDE 3.2.1 with Yast over a FTP server. But now, I have some trouble with sound under KDE and it doesn't work anymore. Whenever I want to configure the sound system in the control center of KDE, the control center craches. Where can I find error messages that help to find out the reason for the crash? Are there any known problems with KDE 3.2.1 and sound systems (ALSA, OSS, arts) ? Thanks for your help, Christian
