Well, the kde3 libraries. But if you have pulseaudio I am pretty sure
this is the problem.

'sudo apt-get purge pulseaudio' should do the necessary. Make sure you
also remove gstreamer and vlc-pulse, if this is not done automatically
already by the above command.

Removing ~/.kde/share/config/phonondevicesrc is also a good idea after
that, just to make sure it really removes the unnecessary backends.

Configuration for phonon is in System Settings -> Multimedia. You will
still have pulseaudio showing there, but it should be at the bottom.
Make sure you have the xine backend showing in the 'backend' tab of
that GUI
