You could try powertop to get more information. There is a "Device stats" tab
where you can see whether the hardware uses too much power too. If so, you
could try to apply the items in "Tunables" that apply to "Audio".

On battery? Does this happen right after a reboot? Or only after watching some
flash videos or such things? IIRC pulseaudio adapts latency to its clients. If
there is a client connected that wants minimal latency, wakeups will rise.

Not for me.

Not normal, too. Maybe caused by the hrtimer_wakups.
