AVAudioSessionDelegate called at endInterruption, but beginInterruption not called

Question

I\'m setting up an AVAudioSession when the app launches and setting the delegate to the appDelegate. Everything seems to be working (playback, etc) except that beginInterrup

Answer 1

I just checked on my iPhone 5 (running iOS 6.0) by setting a breakpoint in the AudioSessionInterruptionListener callback function that was declared in AudioSessionInitialize(), and this interrupt callback does, in fact, get called when the app has an active audio session and audio unit and is interrupted with an incoming phone call (Xcode shows the app stopped at the breakpoint at the beginning of the interruption, which I then continue from).

I have the app then stop its audio unit and de-activate its audio session. Then, on the end interruption callback, the app re-activates the audio session and restarts the audio unit without problems (the app is recording audio properly afterwards).
