title: How can I get background music to restart after an interruption such as a call
body: <p>Background music in my game works fine and plays behind other sounds that get activated. The back ground music is in Did Move to view and is a SKAudionode.
  When a call is received the background music stops and does not restart even if the home button is pressed and game restarted.</p>
  <p>I have seen some other topics but they all seem to be related to AVAudioplayer which I have tried for background music but it gave me a different set of issues so I would prefer to use SKAudionode.</p>
  <p>The code for the background music is below. Any help would be appreciated.</p>
  <pre><code>var backgroundMusic: SKAudioNode!
  
      override func didMove(to view: SKView) {
      if let musicURL = Bundle.main.url(forResource: &quot;playlistbj&quot;, withExtension: &quot;mp3&quot;) {
      backgroundMusic = SKAudioNode(url: musicURL)
          addChild(backgroundMusic)}
  
  }
  </code></pre>
