Comment 23 for bug 479375

I have had exactly the same bug and following the advice in that thread fixed it perfectly for me, my audio works with no flaws whatsoever since I changed the power_save value to 0.

 Hm, somehow I got rid of the problem.
 After playing around with the power_save value in /etc/modprobe.d/alsa-base.conf. I changed it to 60 and the dropouts disappear. However when I temporarily switch back now to a value 10, it is very difficult to reproduce the dropouts. I did otherwise not change anything in the system. Can anybody confirm that? What about you, David Finch?

It seems a bit of a mystery. But I guess it's safe to say, even though my symptoms are somewhat different, that this is related to the power-management setup issues that people had e.g. here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/381201 ."
