title: sencha touch: how to play audio and hide the player from view
body: <p>The audio example on the Kitchen Sink doesn't seem to work since I'm not hearing anything or seeing any player on the screen. I don't know if my browser or my laptop is not working properly but I'll take the risk of asking here if there really is something wrong with the code.</p>
  
  <p>The usual code for including an audio file in Sencha Touch is usually like this:</p>
  
  <pre><code>{  xtype: 'audio', url: "who-goingmobile.mp3"  }
  </code></pre>
  
  <p>This was the sample code shown in the Sencha Touch API. I've tried doing it but the audio player still won't play or show in my browser. Please help, thanks.</p>
