I have a home projector we use for outside movies. We downloaded the movie Jaws and were able to use our fire stick to play the movie except there was no sound. We tested with other movies etc and no problems. So we then bought the dvd from the store thinking it was a problem with the digital service for that movie. Well, the dvd on the DVD player (hooked up to home projector)would not play sound either. We tested with digital versions of Jaws 2 etc but those worked fine. The movie plays on our TV fine. So, it’s JUST the original movie Jaws that won’t play sound when connected to the movie projector. Is there a way to solve this?
I think there's no problem with the devices you are using, it just so happened that the specific movie you are playing doesn't have any sound other than the movies you are watching, Just keep on watching digital movies that are working well with your projector.
