C-Media AC97 driver not work after windows update

I have downloaded “C Media Electronics Incorporation - Sound - C-Media AC97
Audio Device� from Windows update which has stopped by audio card from
working.

Under control panel > sounds (on XP Pro SP2 with all updates) no audio is
available

Device manager shows

C-Media AC97 Audio Device
This device cannot start. (Code 10)
Click Troubleshoot to start the troubleshooter for this device.


I think the soundcard is built into the mother board which is
---------------------------
MSI
System Model: MS-6380
BIOS Version: American Megatrends Inc. 07.00T
-------------------------


SysInfo shows the following for sound
-----------------------------------------
Name C-Media AC97 Audio Device
Manufacturer C-Media
Status Error
PNP Device ID PCI\VEN_1106&DEV_3059&SUBSYS_47104005&REV_10\3&61A AA01&0&8D
Driver c:\windows\system32\drivers\cmuda.sys (5.12.01.0049.1 (63), 1.27 MB
(1,332,544 bytes), 12/05/2005 14:21)

As I am not the only person this has happened to can Microsoft please fix
the issue, and before anyone says you should not download drivers from
Microsoft or if it not broken don’t fix it, I would like to point out that
the driver should still work regardless of this.

First off, create a restore point: (Just in case you want to go back, or something goes wrong.
You never know with MS...) Click Start, Programs, Accessories, System Tools, System Restore

Click Start, Settings, Control Panel, System
Click the "Hardware" tab
Click the "Device Manager" button
Click the + on "Sound, video and game controllers"
Right-click "Vinyl'97 codec combo driver (WDM)", select "Properties"
Click the "Driver" tab
Click the "Roll Back Driver" button and roll it back.
Reboot the computer

You won't get a choice when rolling it back, so just go with whatever it selects.
When you roll it back, Windows might complain about the driver not being certified, but just
continue anyway and restart when prompted.
