My Sony Bravia model 40S310 does not have an optical outlet and the LG3530 Soundbar only has an optical input connection. What kind of adaptor do I need to connect the RCA outlets on the TV to the optical input of the soundbar? After I make these connections, What adjustments do I need to make to my TV to listen to the sound from the speakers? Thanks in advance for your help for a soundbar Newbie!
