I'm using ubuntu oneric
with empathy 3.2.0.1
and gnome-shell 3.2.2.1-0ubuntu0.1
. When I use empathy with unity, I receive a notification sound every time someone send me a message. But When I use empathy with gnome-shell, I only receive a visual notification on the bottom-center of the screen, without any sound.
Does anyone know why this is happening?
