Windows 10: reinstall dolby audio driver

I just upgraded from 8.1 to 10. Since then I get the message logging in that Windows cannot open dolby audio and to reinstall. Sound is barely audible thugh it was fine with Windows 8.1 found one on Wndows driver download page but, though I got notice it downloaded successfully, the problem persists - i.e. message doby failed to open - and sound is still barely audible. Any help greatly appreciated. At 75, I'm hard of hearing despite $6,000 pent on hearing aids.

Dolby Advanced Audio and Dolby Digital Plus Advanced Audio

I upgraded to Windows 10. On the Control Panel, both Dolby Advanced Audio and Dolby Digital Plus Advanced Audio are listed.

Neither one is listed in Device Manager. When I click on Dolby Advanced Audio, It says, "Unable to start the Dolby Audio Driver. Restart the computer or reinstall the driver". Clicking on Dolby Digital Plus Advanced Audio the app opens. Do I really need both?
Both are listed on Programs and Features.

 

Dolby Audio Missing

My pc came with Dolby Audio installed, it worked fine before the new Fall update but now after a lot of clean reinstalls, it is still missing. In my sound card properties page, it says that Dolby Audio is enabled in the Dolby Audio tab but when I search
for Dolby Audio to bring up the control panel, like I used to, it doesn't come up. Its not in the start menu or anything. I have reinstalled Windows and the sound driver numerous times. Please help, I want my equaliser back!

ks for the quick action

 

OK, thanks for the model info.

1. Try running the audio Windows Troubleshooter.
To find all of the troubleshooters, go to the search box and enter Troubleshooting. Open the Troubleshooting Control Panel and select View all from the left pane. Choose "Playing Audio" Didn't work?

2. Try Windows Update, may have a generic audio driver to install for your device. Didn't work?

3. Next, would be to go into "Device Manage" uninstall the audio driver, scan for hardware changes, then update the driver. I can walk you through the process, if you need help here.

And if all else fails, we can try finding a driver on the Lenovo website for your device.

Dear John,

Thanks for the info. Unfortunately, your suggestions did work. Sorry for my delay in getting back but I had an unexpected stay in the hospital with a heart attack. You offered to walk me through some other options, which I would appreciate very much. Again, the problem is that, on start up, I get a message that Windows 10 couldn't open the Dolby audio driver and to reinstall it. I don't know where that driver is to do so. I should also note that I DO get sound, but it is very weak where, before updating to Windows 10 from 8.1, it was satisfactorily loud. I don't know whether to expect you to get back immediately or will contact me for a time. I'll stay on-line for a while. If I don't hear from you in a fewminutes I'll look for a message from you. Thanks again for your patience and assistance. Frank

Dolby Audio is not a driver, its an app which will be enabled if the chip and the license is enabled.
Unfortunately, Lenovo lists 2 audio drivers fr your model, one for Conexant, one for Realtek.
Both don't offer drivers for Windows 10, however, if you have a Realtek Audio, then you can use also the the driver for the Ideapad 430:

I downloaded the above package and can confirm it includes also the Dolby application

Did you try to Uninstall the Dolby and Audio Drivers, Reboot and Install the Original 8.1 Audio Drivers?
I have the same problem, doing as above solves the issue.

 

Dear Adalwar,
First, thank you for the reply.
I am novice at this so please excuse my naivete. My original question was where to find the dolby driver so I can do what you suggest. That is, if I uninstall dolby, isn't the driver erased from my computer? In short how do I find whatever it is I have to reinstall? Frank

I believe the Dolby will be Installed along your Audio Drivers. At least in my Lenovo z710 it is like that, that means I have no extra or standalone driver for Dolby.
My Windows 8.1 Drivers are working perfectly in Windows 10.
Normally , in Drive D: there is folder containing all Lenovo Drivers for your Laptop.
Look if you find the Drivers , also at Lenovo Site there are the Drivers for your Connexant Sound Card, although for W8.1, but they should work in W10.
Also in Control Panel there is a Icon for Dolby with a Blue Button on top Left, to switch on/off Dolby. Give it a try.
