Are you able to extract the files to a separate folder or did you just click the file and it ran its own 'setup.exe' type of file?
If you can extract the files, go back to Device Mgr, right click the PCI Device, choose Properties and then click Update Driver........Choose 'a specific location' and then browse to the folder that has the files you extracted and click OK if the button turns black.
If this doesn't work, there is a very good possibility that the PCI Device isn't even a sound device, so then try browsing to the C:\Windows\INF folder (type it in if you can't locate the folder with XP) and try C:\Windows\System32
If this still doesn't work, try right clicking the PCI Device, choose Properties and put a checkmark in 'disable in all hardware'.......then reboot the computer and see if the sound is working. It may be interfering with your audio and that will help you trouble shoot at least until we can help you figure out what the 'device' really is.
So I bought a new computer and everything worked great. I thought that since it came with a lot of excess software I'd reformat, so I do. I install windows XP Pro Media Edition onto the computer as well as service pack 2. I try the driver cd for the motherboard and it doesn't work (as Intel says on their website).
So I download the drivers myself and get everything working but the sound card. It comes up as a "PCI Device" under device manager in the unknown devices categroy.
I got the drivers straight from Intel but they don't seam to work at all. I even tried manualy configuring this so called "PCI Device" with the drivers but no luck, under sound options everything is still greyed out.
