To hook up a Samsung Soundbar, connect it to the TV and the external device using HDMI cables. Power on all three devices and set the source to use the Soundbar. The procedure varies based on the specific version of the Soundbar, the television and any external devices.
A Samsung Soundbar with two HDMI cables allows you to connect a television and external device to the Soundbar, so all audio plays through the Soundbar. Connect one end of an HDMI cable to the Soundbar's HDMI In port and the other end to the external device's HDMI Out port. Common external devices include cable boxes and satellite receivers. Connect one end of the second cable to the Soundbar's HDMI Out port and the other end to the TV's HDMI In port.
Turn on the external device, then the Soundbar and finally the TV. Set the Soundbar input to HDMI using the Source button on the remote control. You may also need to set the TV. Once you connect the cables and set the source, audio plays through the Soundbar.
For a TV that supports Audio Return Channel, use HDMI cables to connect any external devices to the TV. Then, connect the Soundbar to the TV using an HDMI cable. Plug it into the TV's ARC port.
