So I just reformatted my hard drive and reinstalled Windows XP Home Edition. Everything works fine, except for the sound, which is actually a lot more inconvenient than you would imagine.

I've been looking all around and tried several methods to locate this driver, but I've had no luck. Anyone have an idea as to how I can fix this?
