Verify whether the TV has an ARC label on one of its HDMI ports.

If the TV has no ARC label on its HDMI ports, connect one end of the HDMI cable to any HDMI port on the TV and the other end to the HDMI OUT (ARC) on the Soundbar or Home Theater System. Then connect an optical cable to the optical output port on the TV and the DIGITAL IN (TV) port on the Soundbar or Home Theater System

Note: If you cannot connect the TV and the home theatre system or home audio system using an optical digital cable, use an audio cable instead.

Check the volume

1. Increase the soundbar volume by pressing the volume button on the remote control.

2. If you are using a set-top box that has a volume setting, increase the volume on the set-top box (preferably to the maximum setting, or close enough). Then, adjust the volume on the soundbar itself to obtain the desired volume.

3. If the soundbar features the VOICE mode function, try to activate it to make the dialogs clearer. For more instructions on availability and modification of this setting, refer to the soundbar’s user manual. Manuals are posted on your model support page.
