I struggle to play normal audio CD with Rhythmbox, it shows and error "no gstreamer plugin for CD-source found " (not the exact english error message but translated from German). Same error with Soundjuicer.
In Nautilus I can mount the audio CD and play the files shown with Celluloid. I can also play the CD with VLC.
I checked that all gstreamer plugins are installed, so no idea what is missing here.
