I just installed a new Rampage III Formula board and have issues with the integrated sound card. There is background noise in the audio. I have reinstalled Windows and all the drivers and still have the problem so was going to try a discrete sound card. I happened to have a X-Fi Supreme FX sound card from and old Rampage II Extreme board and was trying to get it to work, but the device manager will not even see the card. I have shut off the on board sound in BIOS but to no avail. The question arises as to whether it will even work in my board or is it propitiatory to the Rampage II Extreme board??
