I have a cm cosmos 1000 and my mob is x58. I have all of the wires from the front of the case hooked up. I have 1 cable left that has 2 ends on it. One says AC 97 the other one says hd audio. There is a place on my mob that has cfpa and right beside it there is one called spdif. Does Ac 97 and hd audio go there. Not sure any help would be great. Thanks
