gnome-media-2.22.0-2.fc9.x86_64 I just spent a bunch of time with drago01 trying to debug why I had no sound coming out of totem or rhythmbox, but did out of everything else. Apparently, the default is set to use 'goom' for audiosink and musicaudiosink. I tweaked it in gstreamer-properties but it only changed audiosink. Manually tweaking musicaudiosink via gconf-editor allowed me to get working sound in totem.
You need to change it in gnome-sound-properties, and you shouldn't need to use gstreamer-properties in the first place, it's a debugging tool.
