title: Audio is not playing in Facebook app
body: <p>I have a small HTML5 game with Javascript and JQuery. Every thing is working fine but the audio is not playing when the application starts.</p>
  
  <p>I have used "audio" tag to play the sound.</p>
  
  <pre><code> &lt;audio id="backgroundMusic" autoplay loop&gt;  
          &lt;source src="sounds/startTheme.mp3" /&gt;  
          &lt;source src="sounds/startTheme.wav" /&gt;  
      &lt;/audio&gt;  
  </code></pre>
  
  <p>This issue persists in all the browsers.</p>
  
  <p>Can anybody please help or advice me some work around? 
  Very thanks in advance.</p>
  
  <p>P.S. - I think audio tag is not supported in facebook app.</p>
