Dear List,



The app i wrote using Phonon of Qt 4.8.2 works fine for playback when i
compile with PyQt4 4.9.1+sip 4.13.2+QScintilla 2.6.1.
But failed after i upgrade to PyQt 4.9.3+Sip 4.13.3+QScintilla 2.6.2.
(Recompiled one by one.)

After i ask it to play, nothing just happen, except two WARNING got printed
in the terminal:
==========================
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
==========================


OS: Mac OS X Lion 10.7.4
Python: 2.7.3


And every time i launch my app, In the terminal it reports:
==========================
WARNING: Phonon needs QCoreApplication::applicationName to be set to export
audio output names through the DBUS interface
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin
could not be loaded
WARNING: Phonon::createPath: Cannot connect  Phonon::MediaObject ( no
objectName ) to  Phonon::AudioOutput ( no objectName ).

==========================

The app works fine before upgrade.

So any advice?
