Latest Firefox causing AV receiver/projector to freak out.

I have not had any problems until Firefox on windows updated to build 20170118123726 on my home theater PC. Bringing up a Twitch stream will cause an interruption in video to my projector. This will happen when I play movie files and it switches to bitstream audio from PCM. But now it happens with Firefox despite no audio switch on my receiver. If I pause the stream and go look at some other webpages, after a while, it will randomly cause an interruption again. Going back to the Twitch tab will instantly cause it to happen again. It will also happen when viewing a GIF, closing the window will also make it occur. Is there a way to roll back to a previous build?
