Under most conditions only allows stereo sound. I don't want to duplicate the web on why this is so but it's not a technical reason why they do that.
As I can't see the exact model ask SAMSUNG how to emit STEREO PCM Audio. If you supply the full model I'll ask you to look in the product manual first and ask Samsung second.
