Lip sync with Samsung QLED
I cannot get the audio to sync with the picture. The audio is delayed. I only have the problem with the second tv box. I've switched the main box between the two tvs and also exchanged the second box at an Xfinity store. I've tried adjusting the audio delay function on both, the sound bar and the tv and that just makes it worse, since I can only delay the audio more, not move it the other direction.
Streaming movies on Netflix or Amazon works great. It's only when I use the second tv box.
