ALSA Problems

Hi, I've got some problems with alsa and my soundcard (VT8233). Installing it with yast works fine, but if I try testing it it only plays a sound every third time. ALSA via82xx.c:704: invalid via82xx_cur_ptr, using last valid pointer ALSA via82xx.c:704: invalid via82xx_cur_ptr, using last valid pointer ALSA pcm_native.c:1268: playback drain error (DMA or IRQ trouble?) ALSA via82xx.c:704: invalid via82xx_cur_ptr, using last valid pointer ALSA via82xx.c:704: invalid via82xx_cur_ptr, using last valid pointer that's the logoutput. Any help would be aprecciated. Georg
