Do you have Intel HDA soundcard? If so, please try adding the following to your /etc/modprobe.d/alsa-base: options snd-hda-intel position_fix=1 (also try 2 and 3--on my Santa Rosa MBP 3 works the best) Hope this helps! Best wishes, Ico _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
