Fixing G31M-S Realtek Audio Problems on Windows XP

My Sahara "FRAGG" PC uses an ASRock G31M-S motherboard, which uses the Realtek ALC662 Audio Codec. The problem arises when you try to use Windows XP instead of Windows Vista, because the Windows XP driver doesn't seem to install properly.
Even after downloading the WinXP driver (WDM_R213.exe) from the Realtek site, it wouldn't install. Then I did a Google search for "realtek alc662 winxp" and found this HardForum post, which explains how to delete certain "HDAudio" registry keys. I tried it, rebooted as instructed, and was initially disappointed, not noticing that WinXP wasn't finished. After being asked to reboot again, it now works!
