Solved Volume Adjuster not working after 24H2 update.

No matter where I set the volume on the slider, the actual volume will always play at max. This problem only appears to be present with the laptop's built-in speakers, as the volume slider works correctly with audio devices connected externally via USB (Sennheiser Headphones & Plantronics Headset).

I have tried:

• Uninstalling the audio device/driver, then restarting.
• Reinstalling audio drivers.
• Checking Windows update for driver updates.
• Checking Lenover website for updated drivers.
• Running the audio troubleshooter.

My last bet would be to uninstall the update, but I want to try other solutions first. Any help would be appreciated.

My laptop is the Lenovo Yoga C940 15" (81TE) and here is its spec-sheet.

Boot into safe mode to let us know how it went.

I had the same issue on a customer's computer. I used the Sound Lock utility to limit the sound at the desired level. I see you have already tried to update the audio drivers. I would also try to uninstall any audio card software in Settings, Apps, Installed Apps, then Delete the sound card from Device Manager, restart and let Windows automatically install the drivers.

Thanks for the reply. Had the chance to try what you said. But it would appear that audio is not available when in safe mode. Any other suggestions?

All right, I went ahead and hit the nuclear option and rolled back to build 22631.4460 (Settings>System>Recovery>Recovery Options>Go Back). As I predicted, if fix the volume slider issue.

So for now, I'll mark this issue as solved. But I'll note that this appears to be isolated to the 24H2 update.

You can hide that update if you want.

Rather than hide, I'll just ignore it for some time. It's vague, but something like this happened to me before. I downgraded, waited some time, then upgraded and the issue did not re-appear. I'll try that again this time, but thanks anyway.

Most likely when you went back to 23H2 the proper driver was installed and the issue was gone. You didn't have to do that. You could try installing the proper driver in 24H2. Anyway, if you don't hide (block) an update, it will eventually install without asking. So if you really want to prevent an update from installing you must hide it as mentioned above. I would also hide the audio driver update. Now that you have working drivers, see the relevant Tutorial to extract them in a folder. So if you eventually upgrade to 24H2 and you have the same issue, you can go to Device Manager, select the audio card, right-click Update drivers, then second option (manually update), then again the second option (select from a list) and click Have disk to browse to the folder with the drivers.

I figured that it was a driver issue. The thing was, when I went to look for compatible drivers. The only ones I saw (for my machine at least) where the ones I already had installed. Same version number and everything. I even reinstalled them, as stated in the first post.

Now about what you said about extracting drivers, I didn't know one could do that. I'll look into it.

EDIT: You know what, I'll try the update again when I'm not watching lectures, and try to do more than what I already did to fix the issue. I may even stumble upon something that will help other people with the same issue. So while I have you here, other than what you've already mentioned, are there any other possible causes to this issue that you can think of?
