I was also having this issue but have solved it now. This error happens when you uinstall the updated C-Media AC'97 sound driver which installs after upgrading XP to SP2. To solve this, you need to delete the CMAudio from the registry from this key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. You need to find and delete all key related to *-cmaudio*- and *-C-Media*-, not just the string entries, _except_ for that entry in the Run key I mentioned above, just delete the cmaudio -string- for that one. After that run the file that you get from the zip file. Also delete the below files from the C:\Windows\System32 directory:
And then delete everything that you can readily delete from this locations - C:\Temp, C:\WINDOWS\prefetch (XP only), C:\WINDOWS\Temp, and C:\Documents and Settings\%YourName%\Local Settings\Temp. Just dont delete the things that start with hsperfdata_ and Perflib_Perfdata_***.dat files incase you find them. After that go to Device Manager and right click on C-Media WDM driver and uninstall it. After that right click on the top computer icon and hit scan for hardware changes, then it will install a generic "Multimedia Audio Controller".
