What is the ID of your motherboard?

If you do not know try this program:

Post back Mainboard and Chipset and Southbridge

Anyway go to this site:

Choose your Operating System then Audio Drivers

Audio drivers are sorted by Southbridge versions so you will need to know your Southbridge.

Let us know if we can help further.
