Hi again,
I know that mine only lights up if you put a plug in it also asks what you are inserting, IE "front speaker/line in/mic, etc & you tick the box to confirm this.
I know that my line in (blue) works as I do some movie/sound recording to my computer.
As for the others I have never tested,when you installed the drivers etc did you make sure it was the 64 bit ones?
The other plugs only work if you plug something in, the "blue" is 'line in' in mine, while I use the green for my speakers via a amplifier.
My specs" for my "realtek" are; Audio Driver Ver. 6.0.1.6511, Directx 11, HD Audio, Audio Codec, ALC 889.
The only other thing I can think of is you have wired the board up wrong, which I have done once, in my case I missed a couple of wires.
Ben.
