audioqueue stop

Hi,

I have a couple of new issues with audioqueues since upgrading to OS 10.6.7 and Xcode 4.0.2.

Calling audioqueue stop no longer cleanly stops the audio. There is a slight stuttering, like the buffers are still playing after the call for a few msec.

OSStatus err = AudioQueueStop(mQueue, true);

Is there any way to amy sure this does not happen? I thought that the 'immediate' boolean was intended to prevent this.

Second, on repeated looping through my code, audio performance degrades. The playback sound becomes distorted and output volume seems to drop.
 
I am initing and then releasing multiple audioqueues, so it's possible I have a memory leak or other error. The queues still play, but why would the audio degrade?

any suggestions to localize these issues would be appreciated.

thanks,


Robert Carroll
