... for s/pdif in, not out. "Out" has 2 pins and 'In' has 3 pins *side
by side*, no empty space..

I did finally find the polarity for the two pins on the motherboard
but it's not much help since I can't find polarity for the video card.

I suppose I have the proper cable because, as I said, there is a small
cardboard saying that "The four-holes black header goes to the
internal S/PDIF-Out header on the motherboard. I will remove the video
card to check if polarity is indicated.
