If Amarok does not play anything, you hear no sound or it skips through songs,
you are probably using Phonon GStreamer backend. To fix this either:

1) Install phonon-backend-xine package and remove
   phonon-backend-gstreamer package (with your favourite apt package manager).

2) Install phonon-backend-xine package and make sure Xine backend is preferred
   to GStreamer. To do the latter, go to `[ Menu ] Settings -> Configure Amarok
   -> Playback -> [ Sound system configuration ] Configure -> [ Tab ] Backend`
   and move Xine to the top of the list.

Finally, restart Amarok. See [1] for more information.
