Audio Architecture (UAA) High Definition Audio class driver. This is either the KB835221 (for SP1) or the newer KB888111 (for SP1 or SP2).
If you've already tried your hands installing the Windows XP SP3 RC v3264 and you have a High Definition Audio device on your computer, I bet you must be having problem with the audio drivers as am I. When you try installing the KB888111 which works for SP1 and SP2, it will not work for SP3, at least for the current SP3 RC v3264 and you will be prompted with a message saying that the current service pack installed is newer than the fix you are trying to apply. Even the older KB835221 doesn't work.
So, is there a way to fix it? Fortunately, there is.
Well, all is not lost. You can try tinkering with the INF file to make your Windows which is installed with SP3 to think that the KB is meant to be installed on SP3. redxii from msfn forum did just that and created a modified KB888111 which is available for download.
I've yet to try it out but from the feedbacks, they are positive! I've tried it out on my system which is installed with SP3 and it worked! Just download the 7z (7zip) file or zip file below, extract it and then right-click at the ? mark at the device manager that you think might be the Audio device, reinstall the driver by pointing to the folder you extracted the files to. After that's done, install the audio driver for your motherboard. That's it!
Let's hope Microsoft will include the UAA driver in the SP3 RTM and save us from this kind of problem or else almost all audio drivers will need to be updated. That will create lots of problems for the vendors.
Have fun with SP3
