iOS - Playback of recorded audio fails with OSStatus error -43 (file not found)

Question

I set up an AVAudioRecorder instance the following way when my view loads:

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
audioSession.deleg         


        

Answer 1

You may need to set the AVAudioSession category back to playback mode:

NSError *_error = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&_error];

if (_error) {
    // handle error here
}

This should also avoid the problem where the audio will not play with the mute switch toggled on.
