I like having volume control for HDMI out. And I like that this mysterious starving audio, playing silence, glitch has disappeared. But I don't like that pulse uses so much CPU and i think it's a major reason why my computer is runn 5-8 degrees C hotter with gnome3 FWIW, this is almost certainly a bug that can be fixed. In my experience PA allows huge power savings compared to ALSA (down from more than 100 wakeups/sec to less than 10 wakeups/sec).
Try debugging a bit to see what is going on powertop2 should be very helpful.

Tom It could also be that GNOME 3 uses hardware acceleration by default[1]. If weren't running Compiz before, it might be making a difference (I have no idea how it compares if you were using Compiz before).
