I just built a new system with an EPOX 8NPA SLI MoBo with a Sempron 64/ 2800+
The system also has:
1 GB RAM
Samsung 250 GB SATA Drive
Nvidia GForce 6200 by Chaintech
Other than the sound not working, the computer works fine with Windows XP Pro SP 2.
When I go into the sound control panel, all looks good. I can change the volume slider, click the arrow on a system sound. So as far as the computer is concerned, the sound is on. I have tried different speakers and headphones as well. I can also go into the AC 97 audio control panel and it sees the speakers or headphones I try. I have also installed the latest AC 97 driver from EPOX's website for my board as well as the latest chipset driver and updated to the newest BIOs. Operating system temperature, nominal. So.. any troublshooting suggestions are welcome.
