I have worked with Vista 5231 and the sound of my motherboard doesn't work automatically. So I inserted the ASRock mainboard CD and Vista found the sound driver!

In Vista 5270 - English and German version - the same problem: first no sound....
Also the mainboard does not bring help ... at the beginning.

So I told Vista to search at the parallel always installed Vista 5231 folders SYSTEM32/drivers and /inf and the mainboard CD in my DVD/CD drive...and at least I was able to get the sound working!
