A:Answer Hello McPlot, to use the benefits of the pass through, the sound bar does need to be connected in a certain way. The first step is to connect the sound bar and the TV with an HDMI cord that is plugged in to the ARC (or eARC) ports on both devices. After that is done, you then attach the device that sends the audio through to the sound bar (typically a DVD player, cable box, or gaming console) in to the HDMI IN on the back of the sound bar.
