I am developing an audio streamer and have declared an interruption listener to save state of a song when an interruption occurs – like an incoming call or an sms.

Here is the relevant code

In my AppDelegate, I have this

AudioSessionInitialize (NULL, NULL, interruptionListenerCallback, self); AudioSessionSetActive(YES);

This is what the interruption listener looks like

void interruptionListenerCallback (void *inUserData, UInt32 interruptionState) { // This callback, being outside the implementation block, needs a reference  //to the AudioPlayer object MyPlayer *player = (MyPlayer *)inUserData;  if (interruptionState == kAudioSessionBeginInterruption) {     if ([player audioStreamer]) {         // if currently playing, pause         [player pausePlayback];         player.interruptedOnPlayback = YES;     }  } else if ((interruptionState == kAudioSessionEndInterruption) && player.interruptedOnPlayback) {     // if the interruption was removed, and the app had been playing, resume playback     [player resumePlayback];     player.interruptedOnPlayback = NO; }

}

When I get a phone call the interruption listener is called and if the user declines the call the playback resume method is also called. But before the resumePlayback method is called, I get this error in the console for AudioQueueEnqueueBuffer
