stream works fine in IE8, IE9 but NOT in IE11

This stream / player works fine in older IE, latest FF, Chrome and Safari, but NOT in IE11
What is going wrong?

Also, when I add a different url (from a different radiostation, for example;stream.mp3) into the player I face the same problem.
But adding this url:;stream.mp3 and it works fine in IE11.

Please help.

Just noticed that adding primary: 'flash' solved the problem.
But isn't that strange? Or do I mis something?

And is it possible that adding the primary flash line into the script has an effect on the alignment of the player?

Please review the following five scenarios that might be at play:

1) Encoding

Please make sure you are using these settings in your encoding: Some browsers are more stringent than others about encoding requirements. I typically use Handbrake (free on Mac) to encode video files.

Here are a few screenshots of my encoding settings:

2) Mime-type:

Please make sure that the request for your video is returning a proper mime-type that corresponds to your video format:

3) Hardware acceleration:

IE has a browser setting called ‘hardware acceleration’ which has been known to break some videos. You can disable hardware acceleration with our player by using ‘stagevideo’: false in your setup configuration (or you can disable the setting in your browser).

4) Mov Atom

The ‘moov’ atom in your video encoding. This is basically a piece of metadata that tells a video player when the video is ready to play. When creating web-friendly video, it is important to select a ‘web optimized’ or fast-start settings.

If you are using ffmpeg, you can use the following:
ffmpeg -i input.mp4 -codec copy -map 0 -movflags +faststart output.mp4

5) Pseudo-Streaming with Flash

If you’re serving videos to clients with older browsers that need Flash mode, you may need to enable psuedostreaming:
