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!

    OK.

    Open Device Manager. (Right-click on the Start button and choose Device Manager).

    Expand the Sound, Video and Games Controllers section.

    Right Click on the Conexant Smart Audio HD item and choose Uninstall.

    Still in Device Manager, click on Action>Scan for new Hardware.

    The Conexant Smart Audio item will re-appear.

    Right-Click on it and choose update driver.

    Navigate to d:\drivers\audio.

    When that's done, close Device Manager.

    Open File Manager and navigate to D:\drivers\Audio\DolbyGUI and install Dolby Home Theater.

    That should get rid of the error message.

    Hope this helps.
