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. After tweaking both of those, (though I had a problem with tweaking them -- see bug 450584) sound works for me.
Already fixed, update your system. Would be good to test updates-testing as well ;) *** This bug has been marked as a duplicate of 449268 ***
