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>

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

```

you can just give "muted=1" so the video will be muted...
chrome allow the videos autoplay that are muted
