Question: On a website I am building I have a vimeo video embedded. The client needs to keep the sound on the video obviously for people that find it on vimeo. However for her website the sound is just plain annoying. So I need to find a way to mute the audio within the code for the embed. I have googled it but can't seem to find anything legible. As you can see from my code below, I have used the autoplay command within the link I was hoping I could do a similar thing to mute the sound.

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

```

Thanks

Answer: 
Seems like Vimeo is providing an updated library, and the API syntax is a bit different from the old one (Froogaloop). Here's how to mute an embedded video with JS:

```
<!--Add the id attr to the iframe tag to use as a selector-->
<iframe id="embeddedVideo" src="http://player.vimeo.com/video/4415083? 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 the Vimeo API Library-->
<script src="https://player.vimeo.com/api/player.js"></script>

<!--Select and manipulate your video-->
<script type="text/javascript">
    //Select the #embeddedVideo element
    var video = document.getElementById('embeddedVideo');

    //Create a new Vimeo.Player object
    var player = new Vimeo.Player(video);

    //When the player is ready, set the volume to 0
    player.ready().then(function() {
        player.setVolume(0);
    });
</script>

```

Hope this helps out anyone who's using the new library. Documentation is at [vimeo/player.js](https://github.com/vimeo/player.js)
@Gadss answer works great but I found that you need update the iframe src to include the activation of the Vimeo api. Just include api=1 after the vimeo id.

I've also found that this sometimes doens't work on Safari for some reason.

```
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script src="//f.vimeocdn.com/js/froogaloop2.min.js"></script>
    <iframe id="vimeo_player" 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>
    <script>
    var iframe = $('#vimeo_player')[0],
        player = $f(iframe),
        status = $('.status');

        player.addEvent('ready', function() {
            player.api('setVolume', 0);
        });
    </script>

```
