Duplicate audio when loading Vimeo video on IE11

[davidvweb]

Hello, there's an issue loading Vimeo videos with Colorbox on IE11. When they open, the video is played normally but the audio is played duplicated, with a little delay. Once the iframe is closed, one of the audios keeps playing instead of stopping.
It seems like the video is loaded on the background somehow.

You can see the problem on http://www.zestvideo.com/sample-videos

It seem to be a common issue, I've found unresolved notifications of the same error here:

It works just fine on Chrome and Firefox, I only see the issue on IE11.
