I installed Realtek High Definition (HD) Audio driver on my I945P-A7 mainboard . After the system reboot, I found under Devices Manager that's an exclamation mark on " Microsoft UAA BUS DRIVER For High Definition Audio. Additionally, the sound Is not working. What should i do ?

This problem Is caused by a bug of Microsoft Operating System. A patch file need to be installed In order to fix such error. When the system are using HD Audio such as Realtek ALC 880 / 882 /883 / 861 chipset , a Microsoft patch file Is needed. Please refer to following link accordingly In order to download the Patch file from the Microsoft website.
