I tried to run the phonon example code, Music player Example, came with the sdk. It runs well on Windows, but crashes while starting on Mac OS Snow Leopard 10.6.8. This is the crash details:
crash line:
audioOutput = new Phonon::AudioOutput(Phonon::MusicCategory, this);

I believe that this was a problem with Qt 4.8.0. It required dbus to be installed on your machine. There are workarounds like installing dbus on your machine or rebuilding Qt with a patch, but I believe it’s fixed in Qt 4.8.1 so probably just use that.
