Internet Explorer 11 And Html5 Sound Playback

I have a JSFiddle that has both a regular html5

Solution 1:

IE11 was running in this case on Windows 8.1 Pro N. Installing the media pack solved this for me, even though I think it's insane that html5 features of the browser need this addition to work properly, and Microsoft doesn't list the Media Pack as having any impact on any other features (like IE11 or html5) here.
