MoscoStateChangeEvent is not triggered after iMdaAudioPlayerUtility->OpenFileL()

[djscorpion83]

Hello,

After I open a sound file I am waiting fot the MoscoStateChangeEvent to be triggered but it does not.

When I minimize my application the event gets triggered.

How can I solve this problem.

Thank you.

Do you happen to keep the system busy when your application is in foreground?

It works also when I open a dialog. It in not only about minimizing the application.

In addition, the priority of the thread is maximum.

That may be a problem indeed: the audio data is actually processed by the Multimedia Server, in a completely different process+thread. If yours is heavily using the CPU, others can not.
A thing I do not really understand in this thread is that the name "iMdaAudioPlayerUtility" suggests that you are using CMdaAudioPlayerUtility, while MMdaObjectStateChangeObserver and MoscoStateChangeEvent are not used by this particular class.
