HTML5 audio IE9 error: Unexpected call to method or property access

I have a problem with part of my javascript code in IE9.

When I start the page I get an error: Unexpected call to method or property access.

This is my audio tag in html file:

<audio controls loop preload id="musicGame">
  <source src="mp3/ambient.ogg" type="audio/ogg" />
  <source src="mp3/ambient.mp3" type="audio/mpeg" />
</audio>

I'm calling my audio tag in javascript like that:

musicGame = $('#musicGame')[0];

Then I'm pausing it because I have a mute button and I need to pause all songs on my page in order for mute to work.

musicGame.pause();

This is where IE9 throws an error.

Any ideas what could be wrong?
