System > Prefrences > Sound

Click on TEST and i get:
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: no element "gconfaudiosink"

On sounds i have ESD ticked and Play System Sounds ticked but when i try to play one there is no sound, i also have no sound icon in gnome.

mpg123 Soundfile.mp3 Plays a sound file correctly
