Hello JBK, If your Samsung TV has the Q-Symphony feature Q-Symphony is only available when you connect the soundbar to the TV using an HDMI cable or an optical cable. You will also need to change the source on your soundbar to D.IN. To do this, press Source on the soundbar’s remote until “D.IN” appears.
When the Samsung Soundbar is connected, the menu name such as "TV + Soundbar" appears under Sound Output (Settings > Sound > Sound Output). Select the menu. (Example: TV + [AV] Soundbar series name (HDMI) or TV + Optical)
