Help! Sound stopped working on the homepage video

I had read a thread previously about getting sound to work on the home page video. I made the modifications to the jquery.youtubebackground.js file so it stated mute: false. Worked great. When I ran updates for the theme and some plug-ins the sound stopped working. I confirmed the file still states false (and found the file in the vendor folder and adjusted that as well). I even deleted the shapely-companion plug-in, re-installed, and adjusted the .js files again but still no sound. Any ideas?
