We've got the 27RlSS also, ours is a 2011, with the Jenson player. I had to play around with the settings on the Jenson, and finally got the surround sound to work. The cables were already hooked up. I can't tell you how to do it because I can't remember how I did it right now, and our 5er is in for some warranty work. If you look in the book, or on the card that came with it, it should tell you how to get the TV to work on the surround sound.
