Hi, I have recently upgraded my TV to a Samsung QN85A and bought the Q700 Soundbar at the same time. I also have a Samsung HT-J5500 Blu Ray and Sky Q system. However I am a bit confused when coming to wire everything together? I think the TV connects to soundbar using eARC ports, but then I have one additional HDMI port on the soundbar (plus an optical port). What is the best way to connect the Blu Ray and the Sky Q box to TV/Soundbar please?
