Hi list,
I got nasty problem when closing a AUHAL.
in Close()
....
err = AudioOutputUnitStop(mAudioUnit);
checkStatus(err);
err = AudioUnitUninitialize(mAudioUnit);
checkStatus(err);
err = CloseComponent(mAudioUnit);
checkStatus(err);
err = AudioConverterDispose(converter);
checkStatus(err);
...

Does somebody have an idea into which direction I shuld start digging.
It looks like a NULL pointer dereference but the AudioUnit is a black box,
and I do not change its internal structure, so where might this NULL
pointer come from?
Thanks for the attention
Andy
