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.

    This was AFTER installing Apple Quick Time. I have no idea what it has to do with this

    but THAT is when I began having this problem.

    It is still installed and the problem seems to be fixed.

    Dolby Digital Plus:

    Had a version problem it was finding Ver.7.6.3.1 and  expecting Ver. 7.5.1.1.

    Was also getting Runtime Errors: 217 at 0043c5e4 and 217 at 00435962.

    I tried to update the drivers and it kept telling me they were up to date.

     and I was Still getting these errors.

    I was afraid to delete the drivers like others and not get them back, so...

    I rolled them back and then did the update drivers (from the net, found and did an update) in

    Control Panel/Device Manager/Sound....

    After a restart all errors went away.

    Hope this helps.
