I dont know what is SKU. Samsung model UE55NU7402U and sound bar are BOSE Sound bar 700. I put optical cable in tv audio out optical and in sound bar audio in optical. Later turn sound options, turn on audio out optical, later turn on expert settings, turn digital output audio and there are three options (PCM , Dolby Digital and Dolby digital+) but i can turn just PCM.
