I connect to a 6 series 65 inch Samsung tv via hdmi arc, to arc on the soundbar. from the tv receiver to the other hdmi on the soundbar. it starts on D.MI then changes to tv arc. but i am forced to change the soundbar to read hdmi to hear sound and that also selects the right source for the tv. I have checked everything, read everything i can find. It works great once you do this everytime you turn it on, but why oh why the extra step.
