title: How to play audio in background with firefox os?
body: <p>In my manifest file I've add the audio-channel-content in permissions:</p>
  
  <pre><code>"permissions": {
      "audio-channel-content":{"description":"Use the audio channel for the music player"}
  }
  </code></pre>
  
  <p>In my index.html I've got an audio tag like:</p>
  
  <pre><code>&lt;audio mozaudiochannel="content" preload="none" src="http://my-stream-url"&gt;&lt;/audio&gt;
  </code></pre>
  
  <p>I can play my audio stream during 2mn:</p>
  
  <ul>
  <li>The first one when the phone is unlock.</li>
  <li>After 1mn my phone auto-lock the screen and it continue playing for another minute.</li>
  </ul>
  
  <p>Does it possible to play this audio stream more than 1mn after the lock?</p>
  
  <p>Thanks in advance.</p>
