I have an Asus A8S-X motherboard which has an onboard SoundMax sound chip
After reading suggestions that we should run in Windows XP compatible mode here is how I've gone about installing sound on Windows 7:
Insert the
Driver CD which came with your Motherboard
Navigate to the
Drivers Directory > select
Audio > Select the
AsusSetup.exe program; Right Click on the Program > Navigate to the
Properties > looking for the Menu Bar "
Compatibility" and Tick "Run this program in compatibility mode for: "Windows XP (Service Pack 3) Click
OK.
After doing so Click on the AsusSetup to run it
That should do it, just sit back and wait for the Sound Icon to appear on the Menu Bar
No need to restart Windows
