This is my code:

-(IBAction)playobey:(id)sender { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"renegadeyamaha" ofType:@"wav"];
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 
    [audioPlayer play];
}

Answer 1

You need to keep a reference to your AVAudioPlayer in an ivar/property somewhere. It's probably being created and then released immediately before it's had a chance to finish playing your sound.

I wrote a little AVAudioPlayer-based sound player class that might make your life easier:
