Hi there, I need help to configure Ubuntustudio on my machine

[Matthias Beyer]

I installed Rhythmbox.
I imported a song. I clicked on the Song in Rhythmbox. Nothing happened.
Maybe because of missing MP3 codecs. I imported the 
/usr/share/sounds/alsa/Front_Center.wav soundfile. Nothing happened.

... I'm really annoyed!
