Comment 11 for bug 884336

Neither using the module parameter for snd_hda_intel nor disabling PA's timer scheduling worked for me.

Note that I didn't reboot my computer for these tests. Instead I just unloaded the snd_hda_intel module and loaded it again with the position_fix parameter specified on the modprobe command line. If this is not enough, I can do it with reboots, but this machine is used remotely by others as well, so I try to avoid that.
