T420s - Dolby Home Theater issue after Windows 8 upgrade

2012-12-16, 8:25 AM

Hey,

 

I have been experiencing issues with the sound of my T420s after upgrading to Windows 8.

 

The error I am getting is:

 

"The current Dolby audio driver version is 7.2.8000.14 and the software application expects driver version 7.2.7000.7. Please install a valid driver and software application combination."

 

I have uninstall the Dolby driver and reinstall the 7.2.7000.7 (checked it on Program and Features) but again the same problem.

 

Does anyone experiencing the same?

 

Thanks,

Andreas

Hey there guys,

 

I have a possible solution that I'd like us to see if it resolves this issue. As a always, please back up your machine as a precaution.

 

1) Update Conexant Driver to Conexant Audio Software version 8.32.43.0 

2) Dolby Home Theatre v4 is listed at version 7.2.8000.17. This update can be found here: http://support.lenovo.com/en_CA/downloads/detail.page?DocID=DS027444.

Hey there Andreas,

 

Looking through the forums and support site I found a few things for you to take a look at. What is your current version of the software you are using for the Dolby Home Theater? Currently the Dolby Home Theater v4 is at version 7.2.7000.4. An update to this version may help fix your issue. You can find the software download here. Good Luck, and please let me know how it goes. Thank you for being a part of the Lenovo Community.

Hey,

 

Thanks for your response.

Still the same problem, the current version I have now is the one you suggested me to install.

 

Thanks again,

Andreas

Andreas,

 

I found another forum that may provide some deeper insight, this forum here seemed to provide lots of assistance to others that were having similar problems.

 

This solution was provided by one our Guru's , and may lead to some success.

 

Is your Conexant Audio driver up to date? Here are the driver's for reference.

 

Please keep me updated on your progress.

Thanks for the swift reply,

 

I have tried and rolled back the Sound driver (Conexant Audio Software, v.8.32.43.0) as suggested to v.6.., then asked me to restart.

 

And again I am getting the same error:err.png

 

I confirm that my Dolby Theater Driver is 7.2.7000.4. :

This problem is becoming annoying.

Andreas,

 

I can definitely see how this problem would be frustrating. Did you try what Peter had suggested later on by chance?

 

If you are using the Lenovo Preload of Windows, under C:\, there should be a folder named SWTOOLS. In the SWTOOLS folder, go to DRIVERS folder and search for the audio driver to install back to the older version where it works. Usually, the older version of driver that is used in the Lenovo Preload image is in the SWTOOLS > DRIVERS folder.

Thanks.

 

I did not find any drivers at SWTOOLS for audio, however I found some old Dolby Theater drivers at C:\DRIVERS\WIN\AUDIO\PCEE4 which I install.

 

Now the error is slightly different:

err2.png

 

The thing that I don't get is why the error insists that Dolby audio driver is 7.2.8000.14 while it is now 7.2.7000.11.

And which are the two driver and software that have to be combined. 

 

Thanks

Andreas,

 

I want to gain clarification on the driver. When you are in your device manager under Sound, Video and game Controllers do you have a Conexant HD or Realtek HD audio driver? Earlier you mentioned the conexant driver, and I just want to ensure that, so that I may attempt to replicate the issue and try to resolve it.

 

I am digging deeper to see what else I can uncover concerning this issue. Please let me know any updates you may have, Thank you Andreas.

Hi.

 

I have a T420s with the same issue:

I have the Conexant, which is the suggest driver from Lenovo:

The option to rollback is not available to me. Should I uninstall and install the Windows 7 audio driver?

 

Thanks.

 

BTW, how do I add inline image here in the forum?
