I go to update the audio through device manager, it seems to install but then always has warning or ? on it and it never fully installs properly. When I go and download IDT drivers and try and install it it gives me. _ExitError: Error=Device Object not present, restart the system and run setup again. So I dont know if I have the right driver or not or if its some issue with the downgrade from vista to xp. What I do know is that I had it working once before. I tried system restore to before I had replaced the motherboard and that didnt work either.
