I bought a Samsung Smart Tv UN52J525DAFXZA from Sam's Club-- it doesn't have a 3.5 audio output--nor RCA outputs--- I want to hook up a bluetooth system-- it has an optical receptacle but I'm not sure if it's for input or output -- if it's for output is there a transmitting device that I can connect to it? I've read there may be sync (lips) problems, is that correct? many thanks, dickb
