No Media Bay preview when in Dolby Atmos

If I’m in a stereo production, I can hover over and preview sounds in the media bay no problem. When I switch over to an Atmos production, no media bay preview. I’ve checked Google and the forums, and everyone says “your control room is enabled. Turn it off”. My control room is not, nor has it ever been enabled. I’m working with a 7.1.4 setup. All other sounds in the mix play fine through all 12 channels of the Dolby Renderer.

I can’t seem to find any routing for the Media bay. If anyone has any answers or suggestions, please provide!

Thanks,

Jamie
