New ASUS motherboard, driver problems

[The Overseer]

I built my computer today, I have an ASUS P5Q PRO P45 S-775 ATX motherboard. Everything went fine with compatibility and so on, but there's a problem with the audio driver. I think it's the Realtek HD audio driver. I installed the driver from the ASUS CD that came with the motherboard (like I did with all the other drivers) but the computer still treated the audio device as having uninstalled drivers. So I tried installing the HD Audio drivers from Realtek's site, still no detection. It's really annoying, as Windows thinks there's no driver installed, so it tries to install one with its silly detection app every time I boot it up. Sound and audio work just fine, it's just the driver that won't install properly. Any tips on what I'm doing wrong?

Maybe this is a newbie question, but it annoys the crap out of me. I even tried installing the latest NET framework, to no avail. The Device manager just lists it as "Audio Device on High Definition Audio Bus" with a "no driver" question mark on it. I read on the driver CD I might have to install a Microsoft HD audio bus, but I haven't found anything online.

Maybe this should be added to the megathread, don't know if it was motherboard specific. Please delete/move if that's the case.
