are you using foxconn motherboard? then this news is for you, when you install motherboard drivers first you
must install chipset drivers, after installation complete then you
must restart computer (dont just click restart later and continue with other driver installation)
i,m gonna tell you if you dont restart your pc and continue with other installation, your
sound driver wont work, after that there is no way to resolve the issue, the only solution is reinstallation of windows, so dont get lazy, follow the correct order and save your valuble time.
