That's from an Intel chipset. The 8086 part tells you that. And
yet, if I search in a recently downloaded INFINST from Intel,
I don't get a hit on that number.
In this thread, someone indicates it's related to HDAudio.

Same sorta idea here. Now, if I look in an actual UAA hotfix file,
I see PCI\CC_0403 as a Device Instance ID in it. If you check your
list of Device Instance IDs, that might be there as well. The
CC or Class Code is a shorthand for certain standard interfaces
(or interface types), and is sometimes used for matching in .inf
files.

My *guess* is:
1) SP3 service pack has built in Microsoft UAA driver.
2) For users of SP1 and SP2, UAA was available via a hotfix. You couldn't
install HDaudio unless someone provided you with the Microsoft UAA driver.
3) Things like a RealTek audio driver (and others), include the hotfix in
a separate folder. On RealTek, look for "MSHDQFE" as proof of that. Included
hotfix files are kb888111w2ksp4.exe, kb888111xpsp1.exe, kb888111xpsp2.exe.
At one time, the entire Microsoft package was huge, because it had
support for 25 languages, while these approx 700K .EXE files are
just one language. I've never heard any complaints about that, so
perhaps the localization isn't that important.
Note, that there is at least one instance of "getting stuck in a loop"
with the UAA driver from Microsoft. In the sense that, you try to (re)install
the RealTek driver package, and it doesn't work. And it's related to UAA actually
already being present, and it needs to be removed, before a sound driver
can be successfully re-installed.
Recipe here (gathered from a couple places at the time):

So without much to go on (nice positive hits), I'd say reinstall
your motherboard audio. If you're not using the motherboard audio
at all (speakers are wired to your SoundBlaster add-in card), then
just disable HDaudio in the BIOS, and the mess will disappear
from Device Manager.
Good luck,
