Sound will cut out momentarily (usually for no more than a second). The skip is always accompanied by multiples of this message in the /var/log/messages file: Nov 23 22:33:06 hostname ALSA sound/pci/via82xx.c:737: invalid via82xx_cur_ptr, using last valid pointer Nov 23 22:33:06 hostname ALSA sound/pci/via82xx.c:737: invalid via82xx_cur_ptr, using last valid pointer Nov 23 22:33:06 hostname ALSA sound/pci/via82xx.c:737: invalid via82xx_cur_ptr, using last valid pointer These messages appear in the log file once or twice a minute although the sound only noticable cuts out every few minutes . Very annoying on an HTPC. ====================================================================== ---------------------------------------------------------------------- brentcfisher - 12-06-04 02:24 ---------------------------------------------------------------------- tiwai, Thanks for looking into this. The information that you requested is below - captured while playing back a DVD.
