I cant get any sound on my computer. I hear an audible click througheither the frontboard or rear connectors when headphones are plugged in, but the sound wont come through. I have the newest bios, video drivers and the soundmax drivers. All of which install fine, but still provide no sound. I've installed via the autorun, straight from the cd, and from the system drivers folder. My computer is running windows 2000 with service pack 4. Any help?
