I connected the Arc via HDMI - the TV and the soundbar were immediately recognized, the TV turned off the internal speakers, and the soundbar turned on automatically along with the TV. There is also a function that I learned about after purchase - the soundbar can broadcast commands from the TV remote through itself if the soundbar blocks the IR signal receiver on the TV.
