title: Youtube embedded video will only have audio when iPhone not muted
body: <p>I'm developing a mobile website which includes Youtube embedded videos, I am doing this through the <code>&lt;iframe&gt;</code> tag: </p>
  
  <pre><code>&lt;iframe src="http://www.youtube.com/embed/videoID" frameborder="0" width="560" height="315"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>The video embeds OK, and plays as expected, but when the iPhone has the silent switch to Muted, no audio comes out, (with headphones the audio is OK). Whenever I un-mute the iPhone, the speakers work fine and the Youtube video works perfectly...</p>
  
  <p>Is there a way I can override the iPhone silent switch so that the speakers play the video even when the iPhone is muted? </p>
  
  <p>Many apps, including the native Youtube app work fine with the speakers even when the iPhone is muted, since these are all user-initiated audio events...</p>
