fixing a Windows universal audio architecture error

First Step is to make sure all instances Realtek Audio
and its associative softwares are
uninstalled from add remove programs and device manager.
This includes Intel High Definition audio.
On your PC change the CSDVersion registry key to Windows XP SP2:
HKLM\SYSTEM\CurrentControlSet\Control\Windows\CSDVersion value=200
This problem arises as the patch thinks that SP3 includes a
better version of the patch itself and hence doesn’t install itself.

3. Download the latest drivers from the Intel website,
navigate to the KB888111 patch.

4. But before installing the patch, goto your device manager and
disable the UAA.
Now uninstall the UAA.

5. Install your patch now.

6. Install the Realtek drivers now and things should work.

7. Change the SP version to 300 again.

If it didnt work, try once again. I can enjoy 7.1 channel
high definition sound
from my Intel Original motherboard now. Realtek HD Audio
now works fine.
Hopefully Error 0xE000027 is fixed now.
