cant even install this driver. Keep getting cant verify publisher of this driver software. Keep klicking install it anyway but it wont go away.

I hate giving up, but I think it's time for a new "clean" installation.

I've got EXACTLY the same problem, i'm following ten forums at the same time, but nobody came up with solution. CLEAN INSTALLATION DOESN'T WORK, so don't do that. I also have unknown device... And can't install AC '97 also. Also Intel Chipset. After a week of struggling I think that it is about those unknown devices, or software(maybe drivers, but we tried everything what is on the market and nothing works). Today I downgraded to XP and there sound wasn't also working(it was before upgrading to Win7). So I'm back again on Win7. Anyone any ideas?

Try downloading this freeware utility.

It may identify n the Unknown device

Unknown Device Identifier - Freeware Download

after opening it and trying to detect is shows error: Privileged instruction.

You need a higherr end graphics card

so there's nothing I can do?

I'm having the same audio problem. Fatal1ty F190 HD motherboartd, Radeo Xpress 1250 onboard video, ACL888 (Realtek) audio. Downloaded latest Reatek drivers (11/19/09). Tried to install Reatek HDMI audio driver and go "no drivers are supported in this package." Ran compatabilty check and found the latest HDMI audio package is compatable with XP. I'm running Windows 7. I have spent hours on this problem and have been to numerous forums. Reatek needs to get on a stick, because a lot of folks are having the same problem.

Well, I installed Windows 7 x32, not x64 I now I have sound. By the way, I had no sound with Vista x64 also, but with Vista x32 I had sound. However, both Windows XP x32 and x64 had sound.
I am almost happy

i tried it on my and on Win7 x64 and x32 it doesn't work. The same with Win XP. It was working on Win XP x32, but after i installed Win7 and installed WinXP again it wasn't working at all:/
