re: LG Sound Bar not working with Directv/LG TV

I don't see an issue, unless there is some oddball setting somewhere on your TV... assuming your soundbar input is set correctly. I use the same layout with a Vizio TV and Sony soundbar. Are you sure your connection is good(do you have light at the other end of the cable, when connected to the TV)? I've noticed that optical connections can be kinda fickle sometimes.
