“Trying a Polk Signa S2 soundbar via HDMI cable into ARC port. I can't get any sound? Will it work this way or do I need the optical cable? The Polk website says is should provided HDMI is ARC and CEC enabled. I did disable speakers, but no sound.”

• IF you do not use the optical cable, the soundbar must be synced to the tv via bluetooth, which the tv does not have.
