Almost correct.
Phonon does not send any sound anywhere, it tells the backend (which could be 
xine) to do play something.

Maybe Phonon is configured to use a different backend, GStreamer perhaps, and 
that one's config is not suitable for your audio mixing setup (Pluse Audio, 
ALSA mixing, hardware mixing, etc)
