The biggest problem with these is that if they are the ones with sound, you’re gonna have a hell of a time finding a company that can do it. And when you do, your eyes are going to water when you see the price.

My parents have a projector for one of these and it would play sound. Unfortunately they are 3000 miles away and are not technical people. If I can get back there, I’m gonna see if it has a line out. If you can find one, and it works, you could capture the audio separate and sync it up in Avid or Resolve or some other NLE.
