3.1 & System Sounds

They don't work. Hello SuSE people, After upgrading from kde 3.0-5 to 3.1 I have lost my system sounds. MP3's, cd's, .wav's all work. I have checked in control center and aRTS seems to be set up properly and plays the "test sound" OK. Then went to "system notifications" and double checked that certain events would play a sound. Rechecked the box that says enable sound for all events. I have gone over this at least six times. Still no system sounds. Anybody else have this problem? Any suggestions? Bob S.
