Installing Microsoft UAA on XP SP3
Today I had an issue with Microsoft Windows XP Service Pack 3 with HD audio/modem devices that are not recognized even after installation of proper drivers. This happens because they require that the Microsoft Universal Audio architecture driver be installed first.
After a long search, I found a registry trick that allows the Microsoft UAA driver to install.
The file name that is actually needed is kb888111xp2.exe which Microsoft does not publicly available, but it can be found on the Internet. An alternative is to download the driver for your audio device from the hardware manufacturer and extract it from the download. In some cases, the driver will actually install it, sometimes not.
