The weird thing about those files (the two .exe I unzipped), is they're dated
8/18/2004. Which implies they were released well before SP3. So maybe they're
a bug fix compared to 888111 ? (Or added Win Server 2003 compatibility ?)
I don't really understand the history of the UAA releases.

I keep the files from my WinXP SP3 CD on the hard drive, and
the SP3.cab file has hdaudbus.sys in it. The version of that
file is Your download, once you burrow into it
with 7-zip and extract the file, is So it seems
the HDaudio files included with SP3 itself, have a later

I know there are some issues with install order for some HDaudio
drivers, but don't really know how you go about resolving them
for SP3. I think my RealTek installed without a problem on this
computer (installed from an OEM WinXP SP3 CD), but because
of the bloat, I've since switched back to my trusty $10 sound
