rhythmbox, no sound
 

Hi,

Installed rhythmbox-0.5.3-0.dag.rh90.i386.rpm (including dependencies libmusicbrainz-2.0.1-0.dag.rh90.i386.rpm and libid3tag-0.15.0-0.b.dag.rh90.i386.rpm)

Everything works fine except that I can't get any sound with Rhythmbox when I try to play mp3s. However XMMS works fine with sound.
If I run Rhythmbox from the consol and then play a file I will get the following message
(I dont know if that makes any sense):

INFO ( 4221: 0) Initializing GStreamer Core Library version 0.6.0

(/var/cache/gstreamer-0.6/registry.xml)

Please, has anybody a clue of what is wrong or missing?
