Ok here is the issue...
I have an ASUS P4P800 Motherboard with integrated SoudnMAX audio. Recently I loaded Windows XP Media Center Edition, and applied service Pack 2, and all the updates available. I rebooted, and all of a sudden none of my audio PLAYS. The OS does pick up that an auio device was plugged in, and starts the SoundMAX configuration wizard.
I have tried everything, I have upgraded the BIOS on the board, I have loaded/reloaded the Audio drivers, downloaded a new driver set fom ASUS, uninstalled/reinstalled all the drivers, made sure everything was enabled in the BIOS. It is driving me crazy!!! Any help is much appreciated. Thanks ahead of time.
