I JUST finished building my PC today, and the sound won't work. I have an Asus A8N5X mobo, and I'm using the onboard sound. The chipset is an nForce4. I've tried using the Realtek AC'97 drivers, as well as the nForce4 drivers. The only time I can get sound out of the speakers is when I open this HP Sound Effect panel thing. It has a "connector sensing" panel, that detects the speakers when they're plugged in. I click the "Start" button, on the panel, and a loading bar starts up, and goes to 100. During this time (like 2 seconds) I can hear my music playing. As soon as it hits 100, I get a very short squeal type sound, and an error message that reads: Access violation at address 004A1A02 in module 'RTLCPL.exe.' Read of address 0000001C. I'm using the plug in the back of the mobo for the speakers.
