Question 8KHA+ onboard audio doesn't work anymore after bios update

When I update my bios the onboard audio doesn't work anymore.
I updated form the October 2001 version. I think it is because of the following thing in the bios changelog: Change AC97 item name. The 11-06-02 & the 4-25-03 BIOS updates cause the same problem.

When I now boot W2k wants to reinstall the onboard audio drivers. When I do this I get the error: Data is invalid. I have tried updating with the latest audio drivers, but all attempts at installing them end with the same message. "Audio Controller Installation Error. Invalid Data."

Has anyone else experienced this problem & what is the solution? All three of our computers give us the same problem after updating the Bios. We were forced to restore to the old version to restore our audio.

I could not aggree with you more, however this is not the case in this instance. We are having some intermittent memory problems that we hoped the new BIOS updates would resolve & we are thinking of upgrading to the latest AMD processors.

Sounds like the Windows registry info no longer matches the renamed audio controller. I think you need to uninstall the audio controller, turn off the audio in the BIOS and see if you can get Windows to redetect it and ask for software. You may have to manually delete all the VIA audio info from the registry while the controller is uninstalled. Windows has a habit of hanging on to the stuff!

Worst comes to worst......reformat and reinstall.

Thank you for your response.

What you are suggesting sounds quite extensive & beyond the capabilities of most owners of this motherboard I am sure. However, I will give it a go since I do have an image backup of the partition.

It seems hard to believe that this does not seem to be a common problem that everyone experiences when trying to update the Bios on this particular motherboard. We have 3 machines with this motherboard and the same problem occured on all three. But, given the age of the updates and the lack of responses to this thread, it seems no one else has encountered this problem before. Oh well, such is life in the world of computers.

Invalid data means that it is not the correct driver.It is trying to install 98 or xp drivers or the files are corrupted.You should use the drivers on the cd first.

Thank you for all your responses. After much research I found the cause & the solution to the audio driver problem. I am posting the solution in case anyone out there has encountered the same problem. Hopefully he/she won't have to go thru the same grief that we had to.

Solution: Microsoft knowledge base article - 810509

http://support.microsoft.com/default...b;en-us;810509


PRB: Issues with Winfast Graphic Adapters

The information in this article applies to:
Microsoft Windows XP Home Edition
Microsoft Windows XP Professional
Microsoft Windows 2000 Server
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Professional

SYMPTOMS
If you purchase and install third-party graphics adaptors, and if you use the installation program that is provided by the manufacturer, you may experience the following symptoms:

The installation completes successfully, but you cannot later install any additional hardware device drivers or other drivers.
Your computer may exhibit unexpected behavior.
Following are examples of the type of error message that you might receive that indicate this problem:

Access is denied.

The data is invalid.

Note: This issue is known to occur with the product Leadtek WinFast Titanium 200.

CAUSE
The Leadtek driver installation program incorrectly changes the security attributes for the Enum branch of the Registry, which is critical for driver installation. As a result, attempts to install drivers later are not successful.

RESOLUTION
To resolve this behavior and correct the changes that the installation program made, use the following command to run the Pnpreg tool from a command prompt:


Pnpreg –l

The following file is available for download from the Microsoft Download Center:
Download the the Pnpreg tool package now.


etc, etc, etc.

Doing the above solved the problem for us. Don't know why it only seem to affect the AC97 audio driver installation in our systems.

Again, hope this helps someone out there.
