"Dear Customer, Please follow the instructions below to see if the onboard audio will install also do download the latest Realtek HD audio driver the link is below. Thank you, When customer has problem installing Realtek HD Audio driver which error or message pops up stating there is error during the Realtek HD audio installation, have them try with the following steps: The Microsoft HD UAA device drivers interfere with the Realtek drivers and prevent them from loading. The cure is to 1) Open the control panel and launch System 2) Click on the Hardware tab and then launch the Device manager. 3) Go to the bottom and click on System Devices 4) Look for Microsoft UAA HD Audio driver. 5) Right mouse click on it and first disable the driver, and then unload it. 6) Reboot the machine. 7) There should be no problem now with loading the HD audio drivers. http://global.msi.com.tw/index.php?func ... od_no=1498"
