hi, I have a set of Yamaha TSS 15 speakers -It has "Digital in" for both Optical and Coaxial. I Want to connect the Yamaha amp to the Digital out on the soundcard. Only problem is... I don't know what cable I need to buy! It needs to go from the SPDIF coaxial port on the sound card to my "digital in" on my amp. Is there a Photo of what one of these cables look like? I have connected the following: * Optical S/PDIF connector. * All Digital cables from speakers. I think this is why my rear speakers aren't working in games properly and the realtek control panel. DTS works in DVD movies since its using the optical cable. what cable goes from the circled ports?
