My old Bose life style 12 doesnt have optical audio connection but only the dolby digital rca cable connection. So far i got the blu ray hooked up on my bose L and R ( red and white) connection and it sounds good but i know if i can hook up the optical blu ray connection to the dolby digital,,,it will be better...or so i hope. Is there some kind of converter that can convert from optical to dolby ? Any suggestions appreciated.
