Give me a few minutes. I can probably find something for you. In the meantime, find the hardware id of the audio device by using the device manager. Right click it, choose properties. Details tab. Change property dropdown to hardware ids. Copy and paste what's there.

Does this do anything for you? Run it in Vista compatibility mode if it refuses to install. If not, give me the info I asked.

This should do well for you.

If it doesn't install simply by running, you should install with device manager after it extracts, using the .inf.

Right click audio device, update driver software, browse, let me pick, have disk, browse.

Open the. inf.
Find a line with this: PCI\VEN_8086&DEV_266E
if there is anything after that, starting with the &, delete it.

For example,
if it's like this: PCI\VEN_8086&DEV_266E&SUBSYS_01821028
make it this: PCI\VEN_8086&DEV_266E instead

Save .inf. Install manually like before.

Windows 7 Ultimate

I used the drivers that Dell has on their site for Windows XP, it worked fine on my D610 with Windows 7:

The device is identified by Dell as a SIGMATEL STAC 975X AC97.
