A:Answer Use an optical cable: from optical out Samsung 8 Series 4K Smart TV to optical in Sony WH-L 600 Base Station.
Or, use a HDMI cable (the most idea):, if the Samsung 8 Series 4K Smart Tv has an ARC HDMI out to ARC HDMI in Sony WH-L 600 Base Station. Make sure the Sony WH-L 600 Base station settings are switched appropriately, in addition to the TV's setting.
Please be sure to use an upgraded optical cable or a HDMI, e.g. Audio Quest..
