phonon queue problem

[Lykurg]

Hi,

I have trouble to clear the queue of a Phonon::MediaObject definitely. I have a "global":

Phonon::MediaObject *phononSound;
phononSound = Phonon::createPlayer(Phonon::MusicCategory);

Phonon::MediaObject *phononSound;
phononSound = Phonon::createPlayer(Phonon::MusicCategory);

To copy to clipboard, switch view to plain text mode 

and a function which can be triggered by the user.

phononSound->clearQueue();
QList<Phonon::MediaSource> soundfiles;
// here soundfiles are filed with 0 to 3 wav files.
if (!soundfiles.isEmpty())
{
  phononSound->setCurrentSource(soundfiles.takeFirst());
  phononSound->enqueue(soundfiles);
  phononSound->play();
}
else
  phononSound->stop();

phononSound->clearQueue();
QList<Phonon::MediaSource> soundfiles;
// here soundfiles are filed with 0 to 3 wav files.
if (!soundfiles.isEmpty())
{
  phononSound->setCurrentSource(soundfiles.takeFirst());
  phononSound->enqueue(soundfiles);
  phononSound->play();
}
else
  phononSound->stop();

To copy to clipboard, switch view to plain text mode 

Now following output occurs:
function called 1st: 2 wav files
-> played 1st wav of 1st call
function called again: 1 wav file
-> played (1st) wav of 2nd call (debug at the end of the 2nd call says that the queue is empty)
-> played 2nd wav of the 1st function call. ???

Why the queue isn't cleared correctly? What's wrong? Various placed phononSound->stop() on different places wont change anything.

Thanks
