Skype not working on Suse 10.1 : (ALSA Error)

Hi, I installed Suse 10.1 and I don't get any sound in skype. I get an error read error, res = -1 , handle = -1 and on the /var/log/messages: May 22 17:01:50 laptopAir kernel: ALSA sound/core/pcm_lib.c:2534: capture read error (DMA or IRQ trouble?) Does somebody have a clue on how to fix this ? Regards Michele
