Re: G780 - Windows 8.1 update - Can't Start Dolby Audio Driver

hi Sperl19,

 

Welcome to Lenovo Community Forums!

 

Your Dolby may not be synced with the Audio driver after the update,

   Since Audio driver may had been updated by the 8.1 but not the Dolby app.

 

Here's what to do:

 

Open Device Manager 

    Uninstall the Audio Device Under Audio inputs and outputs

            Then proceed to Control Panel / Programs / Uninstall a Program

                     Uninstall all Dolby Related programs

                             Restart if Prompted

Now install this software driver

 Conexant Audio Driver

 

Now open Drive C: on the upper right hand side of the screen you will find a Search pane

     Type in "aa" and hit search

You should find 1 of the result as dolby or if not post a screen shot of the results here

 

If ever you found it install that and it should bring your dolby back

 

Hope this helps

Cheers!

Everything worked up until you told me to search "aa".  This came up with 590 results and none of them were Dolby.  It appears the Dolby Driver/Program is now totally gone.  What now?

What's DOS?

Re: G780 - Windows 8.1 update - Can't Start Dolby Audio Driver

Ran both Lenovo and Windows updates and there was nothing there.  Found a program for Dolby for Windows 7 on the Lenovo site and after downloading, it started doing the same initial error message.  Not only that, now my laptop will stick in a black screen when doing a reboot unless I hold the power down to shut it off.  So now we have two problems. Wishing I hadn't installed Windows 8.1.

hi

 The Driver I gave you is very huge (185MB)

      This is because it contains the dolby installer,

         It depends on the Version where it will be located after installing the audio driver
 and what name it will have,

 

Try Searching then for Dolby but make sure you open you drive C: and do the search

or otherwise

      Try Navigating these folders

                 Open My Computer or ThisPC open you Drive C:

Now we'll look for the dolby Advanced audio installer

      Look for these folders as these are through my experience where it goes

                  Also when you find the right folder you will find two of them together (Dolby Advanced Audio and Dolby Home Theater) just install what came with your system the dolby advanced audio.

             C: Drivers / Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)

             C: Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)

             C: Program files x86 / Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)

             C: Program files x86 / Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)
     

Trust me its in your PC now you just need to look for the installer

Hi,

 

I found a solution which may help with several lenovo computers(I have ThinkPad Edge E530): Go to windows Task Scheduler and disable task named "Dolby". I have not noticed any side effects.

I have found a solution to this, coz Dolby Advanced Audio was very important for me... without it, I can never enjoy the movies and music the way I do now... anyways, this is what I did:

 

I went to the Device Manager and uninstalled both the:
* Internal Microphone (Conexant SmartAudio HD)

* Speakers (Conexant SmartAudio HD)

                  under the 'Audio inputs and outputs'

 

Then I went to my LENOVO ( E: ) drive, i.e.my Recovery Drive that has all the drivers and applications that came with my Lenovo G580 laptop... I went to the following directory:

 

E:\drivers\AUDIO\W8-64

 

there, I simply ran the UIU64a.exe application... my Audio inputs and outputs were again restored and then I opened Start Screen, typed in Dolby in the Search field, opened the Dolby Profile programme and there it was, the Graphical Equalizer and all the GUI of Dolby Advanced Audio v2.... its working now as it was working prior to the update... please do tell me if someone else fixes it using the same way or not.... it worked for me.... :smileyhappy:
