I am having this issue as well, also I have to unmute for every video. Is there any way to roll back what you had and fix this in the backend before rolling it out? This makes using your site almost unbearable. If I go through 20 modules, I have to: Hit “Complete and Continue” button after each finishes. This moves it to the next module which starts with the sound off, so I have to hit the button to unmute.
Please roll back, or have the option to use the old player.
