Several players in linux use the Xine engine and Xine plugins to play music.
Any player that relies on Xine will not be able to play MP3's until you download, build and install the newest version of Xine.
Players that use Xine:
Amarok, XMMS, Audacious, KDE Jukebox, Noatun, Totem, and others.
Some players don't rely on Xine and come with their own built-in ability to play MP3 files.
Players that don't use Xine:
RealPlayer, Helix Banshee, KPlayer, and others.
So, if you want Amarok and the others to work, download and install the newest Xine (above).
Make sure you install all Xine packages in the YaST Software Manager before doing anything else.
Download the tar.bz2 file (above), then extract it to a new folder.
Browse to the extracted folder and hit F4 for a konsole, then type:
./configure && make && sudo make install
After installation, test your setup:
You should pass on most tests, with a few warnings, but no errors.
If everything looks ok, install the Win32 Codecs.
