Hi syeve007007,
It seems Intel no longer provide support for this legacy board. Please try updating the sound card driver using Windows Update and see if it works:
1.
Click "Start", input "Device Manager" (without quotation marks) in the Search box, and then press "Enter".
2.
Double-click "Sound, video and game controllers" to expand it.
3.
Right-click the installed Sound Card
and then click "Update driver software…".
If the issue persists, you can try installing the driver for older Windows system in
the Compatibility Mode to check the result.
Besides,
here is the audio troubleshooting wizard from Intel.
