gnome sound

I am trying to get pulseaudio working well in gnome, and it is working pretty well, but I can't get gnome event sounds to work at all yet. (I just upgraded to gnome 2.24).

In the gnome-sound-properties window, the whole sound events tab ("Sounds") is disabled - nothing can be turned on or off. I compiled libcanberra from ports with pulseaudio and gstreamer support.

Does anyone know why this would be?
