MP 1,1-5,1 Optical output not working

[LEOMODE]

On Boot Camp, it looks like optical output is correctly put on (the end part of the cable is lit up), but using Realtek HD Audio Manager program it just is not detecting it. Has anyone faced an issue not making the optical port work? Thanks in advance.

is that just in windows or in osx as well.

if it's just windows it's a driver thing, helps to say what OS and drver you have.
