Few problems with SuSE 9 sound on FSC Amilo M Laptop

Hi all, Recently I installed SuSE 9 Pro on FSC Amilo M laptop (Centrino 1.4). I upgraded it with latest security patches, and also upgraded KDE to 3.2.1. Now I have problem with sound card. YaST finds it, reports it properly, it says that everything is fine, but when I try to play anything there is no sound. It worked properly with out-of-box installation. I tried to change everything possible in KDE Control Center about artsd, but no luck. Any ideas ? Thanks in advance. -- Eng. Dusan Djordjevic (RHCE)
