Audio works, but not MP3 or CDA

I have OpenSuSE 11.2 installed on an Athlon 1.1GHz with 768 MB RAM and 240 GB HDD Space. I have a Radeon 9250 Video card and a AOpen DVD/CD ROM drive. My sound card is an old SB Live that works great. The audio that plays is crisp and clear. My problem is that I cannot get it to play MP3’s or Music CD’s. I have tried looking through Yast to see if there were libraries I needed, but being new to Linux I was tentative to install something that might crash my system.

One thing I can tell you is that when I open an MP3 file in xfmedia or Kaffeine the file appears to open, but is played in a split second with no audio output to the speakers. When I try to play a CD in Kaffeine, I get this error: Cannot find input plugin for MRL [cdda:/].

Other than this most annoying problem, I am loving this system. I have the KDE desktop installed and it works very nice.
