I am having problems getting my version of amarok to play mp3 files. I have done the yum install with these files.

yum install gstreamer-plugins-extra-audio

yum install gstreamer-plugins-mp3

yum install gstreamer-plugins-ugly

yum install amarok-extras-nonfree

After installing these, I still have had no luck with any of it.
I have the latest helix player as my main engine, and have tried using alsa and oss as the output plugin. I also have xine installed as well.

Can somebody offer some advice?

Please take a look at this thread... http://amarok.kde.org/forum/index.php/t ... l#msg13045

It explains how to get mp3 with helix engine.
