How do I connect my old LG 47LG20 TV to my old Auvio soundbar with digital optical cable?

This cable worked from the old Cable Box to the Auvio soundbar. We're in the processing of switching over to FireTV. I've plugged the digital optical cable from the LG TV to the soundbar. No sound from the soundbar. Only sound from the poor quality LG TV speakers. I've tried the LG TV audio settings in both the on and off position - no sound from the Auvio soundbar. What do I do to get sound from the sound bar?

Thanks. I turned the TV speakers off too, that didn't work either. I have changed the audio output type to all 5 of the different settings, Aux, Bluetooth, Optic, Line & Coaxial. It was set on Optic as that was how we were using the soundbar previously. Still can't get any sound. Any more ideas?
