I am getting a odd bug and I wanted to see if jQuery can solve it for me

In summery.  When you play a video and go to the next page then push back the audio from the video is still playing. Can jQuery refresh this or suppress it somehow without breaking anything else =D.
Here is how to recreate the issue:
Follow these steps to recreate the problem: 

1) On the home page, click Watch the Video. Let it play a few seconds. 

2) Close the video (click the X in the top right corner). 

3) Navigate to another page -- any page is fine. 

4) Click the browser BACK button to return to the home page. 

As you'll see (or hear), the audio from the video you started watching earlier will play in the background.
