asus p5kc sound issues

I just built a new machine using the P5KC. Windows XP loaded fine with service pack 2, but I get no sound. Every time I try to update the Realtek audio driver, I get an error message saying the update was unable to be completed. I have the Realtek HD Audio manager in my system tray, and it will play the 3d Audio demo sounds, but Windows wav files and regular audio do not play, and my control panel settings say there is no sound device installed

 

Is the Windows Audio service running?
Go to Control Panel>Administrative Tools>Services
Scroll down the list of services until you find the Windows Audio service.
Right click on it and choose Properties.
Make sure it is set to Automatic and Start is checked.

Are the motherboard drivers installed/updated? This can also cause a problem with audio and other devices.

It's possible not everything below will be in your system to do but follow through and perform any steps you can.
1) Uninstall the Realtek software through Add/Remove Programs
2) In Device Manager, remove the High Definition audio device (or the unknown device, if there is one) under Sound, Video & Game controllers.
3) Go into Device Manager>System, right click the UAA Hi-Def Bus driver.
Disable the device and then uninstall it. (Do not re-boot yet)
