title: Xcode game sounds play in sim and on iPad but not on iPhone 6
body: <p>I created a simple spritekit game.  It works and sounds great in the simulator and on my iPad2.  The game runs fine on my daughters iPhone 6 but the background music and sound effects don't work.  There are no errors.  I checked the volume on the phone even playing some music in iTunes to make sure I could hear it.</p>
  
  <p>Sound declarations:
  located just after the my custom class definition</p>
  
  <pre><code>let tickglass = SKAction.playSoundFileNamed("tickglass.wav", waitForCompletion: false)
  let backgroundMusic = SKAudioNode(fileNamed: "peterpiperb.wav")
  </code></pre>
  
  <p>Locate in playGame function:</p>
  
  <pre><code>backgroundMusic.autoplayLooped = true
  addChild(backgroundMusic)
  </code></pre>
  
  <p>Sound effect when user touches the screen:</p>
  
  <pre><code>runAction(tickglass)
  </code></pre>
  
  <p>All sounds are 44.1 kHz wav files store in a Sounds sub folder.  I'm running Xcode 7.3, and iOS 9.3.5. and OS X 10.11.4</p>
  
  <p>Keep in mind that I'm not new to programming but I am new to Xcode programming.  </p>
  
  <p>Thanks for your help!</p>
