--- Comment #9 from Amar Takhar <verm@darkbeer.org> ---
I decided to give setting kern.hz=2000 a shot.  If I just watch a video it's
fine the problem is actually gone.  As soon as I move a window in X it is far,
far worse.  It breaks up in tune to moving my window and will actually drown
the sound out if I move it fast enough.  This is using optical SPIDF out.  If I
use my external USB audio the problem is the same but the issue is deadened I'm
assuming this is just a difference in the drivers.

I've attached output from messages when I changed kern.hz=2000 for the SPIDF
output.  Not sure if this is a symptom of the problem or from adjusting
kern.hz.
