I installed the Fluendo decoder following the tutorial linked to from here (but just downloaded the RPM so I wouldn’t have to unpack anything). Now “fluendo-codecs-mp3” is showing up in my software manager as having been installed, but I still can’t play MP3 files in either Amarok or Kaffeine. One thing I’ve noticed is that, in the software manager, under “Installed (Availabled)” it says “11-3” in red.
This was such a simple thing to fix in Ubuntu, I’m baffled by how much trouble I’m having right now. Please help me so that I can justify the eight hours I spent downloading openSUSE. I love the interface and would hate to go back to Ubuntu’s oranges and browns (and Gnome).
