A way to mute an iframe using jQuery or CSS?

Question

Is there a way to mute the audio of an iframe using jQuery or CSS?

This is the iframe I need to mute

<iframe src="http://player.vimeo.com/video/4415083?api=1;title=0&amp;byline=0&amp;portrait=0&amp;color=d01e2f&amp;autoplay=1" width="500" height="281" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>

Include this library in your page: https://github.com/vimeo/player-api/tree/master/javascript like this

<script src="//f.vimeocdn.com/js/froogaloop2.min.js"></script>

This code will send an API call to vimeo player to set the volume to 0 once the player is ready, based on http://developer.vimeo.com/player/js-api

// you may need another way of getting reference to the iframe:
var iframe = document.getElementsByTagName('iframe')[0];
var player = $f( iframe );

 player.addEvent('ready', function() {
     player.api('setVolume', 0); 
 });

Or, without the external library:

iframe.contentWindow.postMessage('{"method":"setVolume", "value":0}','*');
