2010.1 System Sound issues

Gnome 2.30.0 desktop, one issue I've noticed and can't figure out how to
correct. Certain system sounds seem to be missing. For instance, when
logging in to Gnome I no longer hear the log-in sound, however, if I
log-in with the 'xguest' user it's there. When mail comes in the system
alert sound is present but switching between windows is silent. Clicking
on, for instance, 'File > Quit' in Evo is silent where it used to at
least 'click'. I'm baffled. Someone on the Mandriva Newsgroup has
suggested I need to use gstreamer with pulseaudio. Not sure how to
configure that though.

Any help would be appreciated.
