follow the cables up to the front panel , you should be able to see which is connected to the usb and the audio
ok, so first of all. what I said about the cables being mislabeled was wrong cause even though all of them are 10-1 pin the HD audio cable has the one pin in a different place. so i started tracing the cables back to the front panel module with the ubs and audio jacks. it was a pain in the *** to reach it and after i almost completely took apart the case and even removed the pcb from the module the audio and usb headers were too close to eachother to tell which went were. so i traced the wiring of the pcb (lol) and it proved that the headers in that side of the cable were identical and were reversed. the hd audio went to the usb2 ports and the usb2 cable went to the audio jacks. so i put them to their right place and everything worked fine.
the weird thing is that the card reader started working too even though i didnt mess with it and its an entirely different cable, but im fine with that.
also I want to add that this was a manufacturing fault of the case and a ridiculous one too. But now that everything is sorted out I still love that case.
