title: AVAudioPlayer is not working in iPhone 5
body: <p>I am developing an iPhone application.In this app i am using AVAudioPlayer for playing audio.
  This is my code for playing the sound.</p>
  
  <pre><code>  NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
      resourcePath = [resourcePath stringByAppendingString:@"/sound.mp3"];
  
      NSError* err;
  
      player_ = [[AVAudioPlayer alloc] initWithContentsOfURL:
                 [NSURL fileURLWithPath:resourcePath] error:&amp;err];
  
      if( err )
      {
      }
      else
      {
          [player_ prepareToPlay];
  
          [player_ play];
  
          int playingLoops = 0;
  
          player_.numberOfLoops = playingLoops;
