I also had trouble getting sound to work with kde applications.
Kde's sound works through Qt's Phonon.  So you have to have phonon
support compiled into Qt.  This depends on GStreamer, and will build a
gstreamer backend for phonon.
Kde will also build a xine backend for phonon, if it finds xine.

The first thing to try would be to open up the systemsettings app and
go to the Multimedia module.  You can then select different output
devices to be the default device, and test them.  The one listed at
the top is the preferred device.  If none of them work, try switching
phonon backends.  Click the "Backend" tab.  The default one is Xine,
if that was compiled, but there should also be a GStreamer one.  Try
making GStreamer the preferred one, and then testing the devices
again.

Hope that helps.
