In Windows XP, if we need to run a High Definition Audio (HDA) device, we would have to install the Universal Audio Architecture (UAA) driver. However, this does NOT work for the latest Windows XP Service Pack 3 Release Candidate Release.
If you've already tried installing the Windows XP Service Pack 3 Release Candidate v3264 with a High Definition Audio (HDA) device in your computer, I'll bet you have encountered problems with the audio drivers as I did.
