I am getting the following error: [0x19bf89310] AVAudioSession.mm:646: -[AVAudioSession setActive:withOptions:error:]: Deactivating an audio session that has running I/O. All I/O should be stopped or paused prior to deactivating the audio session.

If you want to change the app volume, you must

I am currently trying out this code: NSString *path = [[NSBundle mainBundle] pathForResource:@"dream" ofType:@"m4a"]; AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio play]; However, the SDK says that the ViewController does not implement the AVAudioPlayer Delegate. Any body any ideas on how to play a WAV (or M4a) using the 2.2 SDK? You need to add <AVAudioPlayerDelegate> to the end of your controller's class declaration, along these lines: @interface MyViewController : UIViewController
