I've got a Sapphire Toxic HD 4850 and I've got an unknown PCI device in my hardware profile. I've tried to install the HD audio drivers but the hardware wizard won't accept them so I don't know if its the wrong drivers or even a completely different device.

I did come from an Nvidia 8800 GTS, uninstalled the Nvidia drivers, did a driver cleaner and then did installed the ATI drivers. I've also got an Asus P5N-E which is an Nvidia 650i SLI chipset.

Anyone have any ideas what the device could be ?
 
Ive always used an application which detects unknown devices, you can download it at www.driverguide.org and I think its call the driverguide toolkit.

It will give you exact details of the device making finding drivers easy.

Hope this helps.
 
Do you have a realtek o/b sound sound chip on your mobo? If so it could be that it needs the updated "Hi Def" drivers from the realtek site.
 
Microsoft UAA bus driver for high definition audio 5.10.0.5010
everyone gets the missing pci device on 4850's had the same just do an automatic search or google that I presume you are on XP ?

You'll find the driver for that on the CD that came with the card if you didn't use it, i.e you just downloaded and installed the 8.7's from the ATi site, so just let the wizard look through the CD for it.
 
I had to get the UAA hotfix which was the one that was missing ...... found them at the ATI website ... you'd think that the Sapphire, Realtek and Microsoft sites would have them but noooooooooo
 
I don't trust sites like softpedia as they are usually out of date, even then I don't know for sure what they contain (spyware, etc) ... I go to the hardware manufacturers or Microsoft as the only places I'd trust for drivers.
 
it should be in where you extracted the drivers to before installing them C:\ATI

The file should already be on your system it's just xp doesn't auto install it.

It's called "hdaudbus.sys" and (by rights) it'll be in the following directory.

C:\WINDOWS\system32\drivers

Just installed my 4870 sapphire v/c,and installed the drivers off the cd.
have the same problem as you in Device manager,PCI device yellow mark.
i always thought it was like ati rage theater file,which i found was in the sound devices,if you hadnt installed WDM.
I suppose i will just leave it,as everything else installed okay,as i have my own sound card.(If thats the problem)
Did you ever find out what the problem was?
 
Yep, I'd go with the UAA HD Audio driver, I've seen this a few times doing our base images at work, easiest place I've found to get it is HP.
It's a generic file, so don't worry about any mentions of HP.

Failing that, the best thing to do with unknown devices is to:
Right click them in 'device manager'.
Select 'Properties'.
Click the 'details' tab.
Esure the dropdown is set to 'Device Instance ID'.
Highlight the ID (Should start with something like PCI\Ven or HID\ven), press ctrl+c.
Paste this into the search engine of your choice.
With luck, you should find a reference to what the device actually is and be able to source drivers.
 
I had exactly the same with XP and my 4850 when I used the first edition of drivers of the AMD site. Uninstalling and using the ones of the Powercolour disk seemed to sort things out though. No such issues when I formated with Vista and got the latest of the AMD site again though.

Yes sorry ... quick update ..... it was the Microsoft UAA HD Audio that was missing. I went straight to the ATI site and downloaded the UAA patch for XP SP2 and below (XP SP3 already has this). Once I got the UAA patch installed, I then installed the HD Audio drivers from the ATI site.
