@MVman But it's not the Roku that's the issue. See my previous response. Many TVs won't pass 5.1 audio out of the optical connection from connected devices. That's a TV issue, not the device connected to it. My Roku players that connect to Yamaha AVRs all pass 5.1, including Atmos, to my systems. For my players connected to stand-alone TVs, I have no idea how it's processing 5.1, as there's only two speakers available.
