Audio player not playing in ie9

Great plugin. Easy to use and setup. One thing I found though was that the audio player would not “play” in ie9.

The demo works fine but for some reason on my site it is not.

I’m using the genesis framework and have a small handful of reputable plugins activated.

I tried deactivating all other plugins but sermon browser and even changed to the default wordpress 2015 theme but it still didn’t play in IE9.

Here’s a link to the player in question. Anyone have any thoughts?
