Today I upgraded my athlon xp to an athlon 64(reformatted and reinstalled windows), fired up windows XP installed the stuff on the disc that came with the mobo(including the reatek audio drivers) now sound effects work(msn messenger) but when I go to play a song in windows media player or itunes it says no mixers installed, go to control panel and select add printer or other device and install a mixer, now I don't have that option in control panel and I took a quick look in the add hardware panel and didnt find anything, so I decided to ask here since I could probably get a resolution quicker, plus I have to rebuild another computer tonight/tomorrow so I dont feel like spending hours on this.
