I recently purchased the Roku Ultra 4k. I have the Sony AVR with Dolby Atmos. Should I plug the Roku directly into the AVR hdmi for the best sound? Currently I have it plugged into the TV's hdmi with the tv plugged into the AVR's hdmi arc. Sound is good, 5.1 but the AVR doesn't display Atmos. I'm not sure if I'm getting the best sound.
