Set up my system just like the above. Only weird thing is that I have the hdmi going from my arc input on my sound bar to the arc input on my tv which is hdmi 1. Now when I click Arc on the nakamichi remote, it doesnt detect any video or sound. But when I switch to hdmi 4 on the nakamichi remote, I receive audio and video. Everything looks good though and when I hit info it says Dolby on the sound bar. Just thought this was weird because I don’t have anything plugged into hdmi 4.
