Hello, any help or advise will be greatly appreciated. I recently purchased a JBL SB150 soundbar with optical/ aux cable however when i checked on my TV(LG 43LF5400-TB) it does not have either the optical out or audio out at the back. It only has headphones out. I know that its very callous of me to have bought the soundbar first but this is actually my first time and thinking that since my TV is a newer model that it should be compatible.
