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: 
In case it helps anyone, [Vimeo have added a 'background' parameter](https://vimeo.com/forums/feature_requests/topic:278001) for embedding videos, that autoplays videos silently. In some cases that will be useful where people want to mute videos - this is their example:

```
<iframe src="https://player.vimeo.com/video/76979871?background=1" 
    width="500" height="281" frameborder="0" webkitallowfullscreen 
    mozallowfullscreen allowfullscreen></iframe>

```
@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>

```
