Internet Explorer audio problems

I am working on a senior project (an interactive animation), and I am using Construct 2 to make it. It needs to be able to run in Chrome, Firefox, and Internet Explorer. However, Explorer is giving me problems. Whenever I try to run the animation in Explorer, eventually no new audio will start playing. Here is the link to the animation:

Please help if you can.

You should post the capx (the sources) of your project, otherwise there's little to nothing we can do to help.

You can try to check for errors in IE and see where the issue might be coming from.

Like this?

And as far as errors go, I opened the Error Console and then went to the animation. Even when the audio stopped playing, this was the only message to be displayed, and it is apparently just a warning:

HTML1115: X-UA-Compatible META tag ('IE=edge,chrome=1') ignored because document mode is already finalized.

And I have been using Internet Explorer 9

This is always because the server MIME types are mis-configured. Make sure .m4a files are sent with the type audio/mp4.

How do I do that?

The problem occurs when the project is on my teammate's server and when I run it in Construct 2. Is it possible that the problem is with IE instead of the server?

Sounds and music manual entry.

Make a google search for "Server setting MIME type" and apply to your teammate's server.

If you don't know how to set up MIME types yourself, you need to contact your server host or administrator and ask them to do it.
