Crash at [audioController audioQueueIsRunningCallback];

[Shrutimittal91]

I have 4 cameras in my application. While switching between them sometime application gets crash inside function

void audioQueueIsRunningCallback(void *inClientData, AudioQueueRef inAQ,
                                 AudioQueuePropertyID inID) {
    
    AudioStreamer *audioController = (__bridge AudioStreamer*)inClientData;
    [audioController audioQueueIsRunningCallback];
}
