Hi I've just got a htx8500 soundbar just some questions when the soundbar is playing dolby atmos through the soundbar should the atmos white light be permanently lit? Only have the virtical and TV lights lit. The bar is connected via a hdmi to the TV on the earc port.

For some reason the dolby setting on my TV only comes on when the soundbar is off?? Not sure if I've connected it right or if I need a hdmi lead from my sky q box to the soundbar aswell? Any help please
