Can't start Dolby Audio driver after upgrading to Windows 8.1

Lenovo U410 wirh Windows 8 pre-installed.

Upgrade to 8.1 went flawlessly, but every time I re-start or boot up the machine I get this:

I've uninstalled and re-installed Dolby Home Theater, done an extensive local and web search about this.

There appears to be NO mention on my machine anywhere for a Dolby Audio Driver" or anything that uses it.

I've been on the Lenovo forum and there's a thread there that says to disable driver signature, which I've done to no effect.

I still get this message.

Can anyone throw any light on this?

Hi Everyone!!

I did something to my laptop and it worked!!! After messing around the fix was simple!

Of course make sure your computer has all the windows updates. I don't know if that's gonna be a contributing factor, but it was part of my methods.

After that go into your "D Drive" which is found under "My computer" --> "Drivers" -->"Audio"

Once you're in the audio folder, you're gonna scroll down, you will see a computer icon that says "setup" click on that. Once you do that you will follow the instructions. It seems by doing this it updates the conextant audio driver. I don't know why it didn't update in the device manager as others have suggested. But after I did this, I checked to make sure it was fixed

You can see if it was fixed by:

Going into your control panel and clicking the Dolby theater which can be found in the sounds, games, etc. --> you should see the actual program pop up instead of the error message!

I am so glad I finally fixed this! If this helps you, please label it as the answer so everyone else can fix theirs too! It seems to be a major issue

Have an "error" free day!

Hi,

Lenovo has updated the Conexant Audio Drivers for Windows 8.1 to correct this error.  You can download the updated drivers for your device at http://support.lenovo.com/en\_US/downloads/default.page.

    The Uninstall worked just fine. But in my 8.1 (new computer, upgraded to 8.1 last night), when I go to aAction, the only option is Scan for Hardware Changes. No option to scan for *New* hardware. what appears is NOT Conextant, but "High Definition Audio Device". I installed it, & did NOT get Dolby.

    Now I have nothing. Do you have a suggestion for how to get it back? I fear if I do a rollback, I'll have to spend all those hours already spent installing my accounting & business software.  <sad face>  Thanks.

    Lenovo's Official response via the Technical Support Phone call I just made to 877-453-6686 and spoke to Mimi.  They know it's a problem on some devices.  Their recommendation is to wipe it and start over with Windows 8.0  Really.  No driver update since October.  No other solution. This is for the N585 I am working on. Guess it's up to Microsoft to force the issue.
