Polk soundbar, LGtv and Mohu Leaf not playing nice

[boodel]

I have an LG 47lk520, Polk Audio soundbar 3000, both work fine together. Hooked up via optical cord. However, we are looking to drop our satellite. So, I connected the Mohu Leaf via the coax cable, just to test out the reception. Great reception, but there is no sound through the soundbar. There is sound through tv though. Hubby wouldn't be happy if soundbar doesn't work. Is there another way to set it up? I'm totally lost. Tried all the channels/sources on soundbar. Only option in tv is to turn speakers on/off. Thanks for advice!!!

You'll have to use the headphone out jack of the tv to the rca inputs on the soundbar. About the only way since the TV doesn't have an optical out.

thanks, but there are no rca inputs on the sound bar. There is optical output in tv. When connected to dish receiver it works fine. But since we want to cut the cord, need to make it work without receiver.
Don't think I have RCA inputs.

I do have a headphone jack on tv though

Well there 3.5mm on the soundbar then. Thought it was RCA.

Couldn't find the specific manual for the TV only a generic one so it was hard to tell if it had optical or not.

Is the receiver connected directly to the soundbar or the TV then the TV to the soundbar?

Receiver connected to tv, and tv to soundbar. Tried hooking up with 3.5mm to headphone jack, but sound was hissy-even with volume turned way down.
