I joined this board just to say thank you for your post. I know it's 4 years old now but. So anyways I've got 3 hard drives in this PC Win XP, Win 7 and Win 10. My audigy 2 stopped working with Win 10 after an update but the other OS's it...
found this awsome fix and figured i would share it here in case anyone else here is still running this card. (like i am on my mom's pc)
