title: tvOS app doesn't play audio file
body: <p>I have a tvOS app which attempts to play an audio file like this:</p>
  
  <pre><code>#import "NameViewController.h"
  #import &lt;AVFoundation/AVFoundation.h&gt;
  
  @interface NameViewController ()
  
  @end
  
  @implementation NameViewController
  - (void)viewDidLoad {
      [super viewDidLoad];
  
      NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"intro" ofType:@"mp3"];
      NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
      AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL fileTypeHint:AVFileTypeMPEGLayer3 error:nil];
      player.numberOfLoops = -1; //infinite
  
      [player play];
  
  
  }
  </code></pre>
  
  <p>If I put a breakpoint after [player play]; it starts playing for a few seconds.  If I don't have the breakpoint, no audio ever plays.</p>
  
  <p>What am I doing wrong?</p>
