I am trying to connect my old computer to my home theater system. I have everything working but the sound. I saw a product on this forum about 6 months ago. It was made by harmon kardon and basically it took the input from a sound card and output digital coax to connect to the receiver. It seems that I cannot find the product. Does anyone know which product it is? I would also appreciate any other input as to how to connect my computer sound to my receiver. Thanks.
