Hi I'd really appreciate any input. I have an LG50PQ6000 TV and I'm looking to have surround sound. I have a logotech X-530 surround system but my TV only supports digital optical out and not (jack or RGB) I'm only looking to hook up a couple of speakers, so my question is do I need some sort of converter and lead etc (links or the like would be appreciated) or am I just limited to buying a digital output surround system. Many thanks
