I also have stutter when listening to audio under Hardy Heron.
I always set my Windows Preferences to "Select windows when the mouse moves over them". So now I only have to move my mouse to different applications, and sound begins to stutter. As pulseaudio has different settings for each application, maybe this could be a thing to consider, maybe something is broken here.
If I move the mouse very quickly over different windows, Xorg will have a high load (with and without the proprietary nvidia driver.).
