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!!!
