I have an Abit AN8 SLI Fatal1ty Motherboard with an intergrated AC'97 sound card. I installed all the drivers off the disc that came with the motherboard but I get absolutely no output from any of the 3.5 outputs, front and back, no matter what setting I put the sound effect manager to. This problem only came up when i reinstalled windows. The previous windows version on it was Home SP1.
