Deepak/Luke/Mitch,

ALSA: hda - Reduce click noise at power-saving
http://kernel.ubuntu.com/git?p=dtchen/ubuntu-karmic.git;a=commitdiff_plain;h=d6c571bdc08f1958f70c71eb11677066729e8505

This seems worth looking at for power-down clicks.  I'm surprised to
see a 100ms (non-blocking) delay in the power-down path there, though;
not sure what that does if you're powering down on the way to suspend.

- Chris.
