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.

    OK, so i managed to solve this problem another way by going to the lenovo website and installing the newest audio program there. Everything works now, expect I still get that error notification every time I start up my laptop, very annoying. Anyone know how to get rid of this?

    I tried about 15 times to do the steps listed above. It did not work for me

    I  had to completely uninstall the Conexant Smart Audio HD driver and re-install from the Lenovo website. I have a Lenovo Yoga 13. Now that I have done that, Dolby Home Theatre v4 works.

    For those of you who can't get the above steps to work, you can try this:

    Follow steps 1 through 3 above. Once the Confirm device Uninstall window appears, make sure the "Delete the driver software" box is checked, then click uninstall.

    Go to website below and install the driver.

    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.

    Hi Gordan,

    On you set that says navigate to d:\drivers\audio where do I do that? on the device manager page?

    No, Open "This PC" on the desktop or right click the Windows Start button (window icon lower left corner of screen) and select File Explorer.

    Find the D: drive, e.g. Lenovo (D:) and double click to open

    double-click drivers

    double-click AUDIO

    double-click DolbyGUI

    double-click DolbyAdvanceAudio.msi or DolbyHomeTheatre.msi depending on which error message you received

    Follow instructions in install wizard that comes up

    Good Luck!
