LG55LA7400 no sound to external speakers ARC

I have a new LG55LA7400 and a Panasonic SC-HTB20 home theater unit. When I hook up the speakers (ARC HDMI out) to ARC HDMI on the TV and set the TV for external speaker ARC/digital optical I don't get any sound. I have also tried using an optical digital cable between them, but still no sound. My TV input is over-the-air. The set seems to recognize the speakers, but says no input signal? Any thoughts.
