I dont really want to send it back, it's rather like 'the gift horse in the mouth' issue. The sound is noticeably better with the cheap Sound Bar but I can't help thinking that it could be better with a bit of knowledgeable tweaking. The problem is my very limited knowledge of what to Tweak. The amount of user adjustments on the LG TV is bewildering and laden with unrecognisable Jargon. Mr Lucid is very knowledgable on these things, I am keeping my fingers crossed he comes up with a solution .Can you not see if your son can send it back, I know sometimes these things can be fraught with fragile family politics but really I think you're on a hiding to nothing here, the sound quality is poor because it just is. You should be able to plug the optical cable in the back of the soundbar and away you go, absolutely no need for all of this high jinks. Buy a better one, buy secondhand if you want, if you're in no hurry look on Marketplace, at least you can hear them before you buy that way.
