AppleTV only passes through StereoPCM (TVs 17)

My AppleTV (4K, latest version) only passes through a PCM Stereo audio signal to my soundbar instead of a Dolby 5.1 on shows that say they are 5.1. Oddly, Dolby Atmos works fine. I've tried various settings on the AppleTV and my SamsungTV, but I can't get anything but a Stereo PCM audio on non-atmos content. Note: I am using the Beta TVs 17, so I'm thinking it could be a glitch in the new software.
