title: AVPlayer doesn't play more than one time
body: <p>I have some strange problem with playing audio through AVPlayerItem &amp; AVPlayer.</p>
  
  <p>I have recorder and iPod item picker, stream from both of them are going through code like this:</p>
  
  <pre><code>  AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    [audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
    [audioSession setActive:YES error:nil];
  
    _playerItem = [[AVPlayerItem alloc] initWithURL:_soundFileURL];
    _player = [[AVPlayer alloc] initWithPlayerItem:_playerItem];
    [_player play];
  </code></pre>
  
  <p>Everything is actually ok, except one thing, I can't play this stream second or more time. It's just stopped, and no sounds are found after stopping. Does anybody can help with an advice, what the problem could be? </p>
