Glad you got it working. Now for the new issues:

I have not used KDE in a long time but I do know that their aRTs daemon 
takes over sound. Are there any settings showing the left and right 
channels that you can adjust? Maybe called "Balance"? You might also 
make sure that the connector on the actual sound card going to your 
speakers/headphones is plugged in all the way. I know if mine is only 
halfway in then I only hear one channel.

As for CD audio not playing, have you made sure that the audio connector 
is connected from your CD drive to your sound card? It could be that, or 
the mixer levels in aRTs are muted or not raised for CD's.
