title: Autoplay sound in chrome background tab
body: <p>I have an HTML5 game that uses audio notifications.</p>
  
  <p>When users are searching for other players with match-making they frequently change tabs to do other things and rely on the audio notification to know when to come back. This no longer works after Chrome (desktop) changed to disallow audio notifications.</p>
  
  <p>How can I ensure the audio notifications still work in the background?</p>
