Have connected LED televisions via toslink with my Samsung Soundbar. If only the TV is turned on, only the built-in speakers are also used. With activated Soundbar do I control the volume on the TV to 0. There are different sound settings can be selected, for example, Music, Drama and Cinema. Individual settings are not possible. I would prefer if I eg the powerful bass something could reduce without having to simultaneously change the other settings. But for the price still a good system.
