Audio not working after Windows 10 upgrade (Lenovo G780)

After my upgrade to Windows 10 on my Lenovo G780, it seems like my audio isn't functioning anymore. I tried to plug in my headset as well to check if I had audio coming through that, but it does not appear in the Playback Devices window when plugged. 

 

The laptop comes with Conexant SmartAudio HD and also lists High Definition Audio Device under Device Manager. 

 

Could anyone help me out and let me know if there's some problem I am overseeing. 

 

I found a page that has some Conexant software for windows 10 but I am not sure if they are updated drivers or if they even support my machine (the page does not list support for G780).

 

Any help would be appreciated. Thank You.

Re: Audio not working after Windows 10 upgrade (Lenovo G780)

I have a very similar problem. After upgrading to Win 10, I get a driver error with Dolby Audio (although my audio still functions) and am told to re-install the driver or reboot. If I reboot, I get stuck with the dreaded Blue Screen, and the only thing I can do is to revert to Windows 8.1. After reloading Win 10 I've tried several things - deleting Dolby Audio from Programs, uninstalling Conexant drivers for audio,... None have had success and I always have to revert to Win 8.1. Would like Win 10, but doesn't look good right now. Anyone have any other ideas? Very disappointing.

After a couple of tries, I finally got my audio to work and hope it does for you too. What i did was shut my computer down completely as opposed to shutting it down in the hybrid shut down mode. To shutdown your computer completely, right click the Windows Start icon and scroll to Shut down or sign out and select Shut down from the list. Your computer will shut down completely. Turn on your computer again (boot-up will take a bit longer than usual) and check if everything is in order.

As I mentioned before, my audio returned after doing this. Hope it helps.

Re: Audio not working after Windows 10 upgrade (Lenovo G780)

Well, it has been a long road on the Win 10 upgrade. At first I got the same error message as above, but after deleting the Dolby Advanced Audio v2 in Win 10 using Control Panel Programs and Features and rebooting, I got into the continual BSOD upon reboot. Here are the steps I took to at least get stable on Windows 10. First, I rolled back to Windows 8.1 using the advanced feature in the BSOD recovery options. Once back in Win 8.1, I deleted the Dolby Advanced Audio v2 using Add/Remove Programs in Control Panel. Then I downloaded the Win 10 update and re-installed it. Once that completed, I updated the Intel Graphics driver under the display adapters (on my G780 it is an Intel HD Graphics 4000, and the driver can be found at  https://downloadcenter.intel.com/). Currently I am running version 10.18.10.4252 for my machine. Then, under the Device Manager, I updated the Conexant SmartAudio HD driver under the Sound, video, and game controllers. That driver is currently at 8.66.4.50 and was automatically downloaded from the web when I requested to update driver.  I also changed several others settings such as Notify to schedule restart after updates are installed instead of automatic (under Settings --> Update & Security --> Advanced Options) and Do you want Windows to download driver software and realistic icons for your devices? --> No, let me choose what to do, never install driver software from Windows Update.  After that, I shut down the machine, waited a moment and booted back up.

 

I have no idea why this helped or if it is overkill, but I am stable and running without a fear of rebooting now. Hope this helps if someone else is having this same issue.
