My thought is it is a problem with their projector at the theater not reading the audio corretly because the DCP file for sure has all 5.1 and they play back on a computer with audio.

Hello, my friend! I have been reading the website and trying to find an answer to 5.1 mix. 

I have a ProRes 4444 XQ with embed 5.1. After I created the DCP I checked playback in Resolve and all audio channels are present. They all have audio and are playing. In theater, I am only getting the center channel. Please help as I have a movie premiere in 1 week. Thank you!
