Install the Hotfix
Install your HD Audio Driver
***If not working then try to open your device manager and manually install the PCI Device, as long as the hotfix is present or installed just tick Search Drivers automatically. And it should find and install the right drivers!***
When it came to installing the drivers of their soundcard, everything seemed to go as normal, but when they restarted – no sound.
“PCI Device” listed in the Device Manager was infact their soundcard but it wouldn’t recognise the drivers and wouldn’t even let them force the correct driver to install on it – it seems their computer was totally unable to support the soundcard all of a sudden!
