No sound in Amarok 2.1

Just installed open suse 11.2.
I have background sound when I shut down or boot up
When I push play the songs won’t start.
Do i have to download and install an mp3 codec like the last opensuse?
any suggestions,


Also cool streams has not sound

You do still need to install the codecs.
