I found a new nForce 1/2 audio driver for Windows 2000/XP today on Windows Update Catalog. The driver is WHQL certified and driver files are dated 17/01/03. The driver version is 5.10.2922.0 which makes it the latest available nForce audio driver at the moment. Feel free to download it from Windows Update Catalog but if you can't find it, I mirrored the driver here for now (thanks a lot to David again).
