sound error (sometimes) with KDE 3.3 then 3.4 on SuSE 9.2

Hello again Sometimes I get an error message from KDE such as in a window : === error - artsmessage ==== Sound server fatal error: cpu overload, aborting ========================== It can occur for ending a KDE session (a sound is played at this step), or when a software must play a sound. I hoped that an update of KDE 3.3 by 3.4 could solve this problem. This is not the case. I use ALSA sound system. What can I do ? On the same laptop (Asus L5D), there is a SuSE 9.0 AMD64 with KDE 3.1 : no problem with sound. The sound card is an Asustek nForce3 model. The main loaded module is snd_intel8x0. Kind regards Pascal
