Windows 10: Sound Volume Always Automatically Go to 100 After Latest Windows Update

So my sound volume bar is broken, sound is there, but somehow always adjust automatically to 100, even when I scroll it down to 10 or any number, it forces itself to go to max. 100... I mean who even wants to listen to max volume like this in a closed room.It happens when I use a Bluetooth speaker or NVIDIA or everything else. No matter what the device is, it just adjusts to 100 max volume. I don't know which driver to fix.This happened after yesterday's windows update. My PC was just fine the day before.Also, my mouse scroller/keyboard is not broken. Please help!

Low sound volume in headphones - Windows 10

I have same problem

my new notebook is windows 10 2004 intel 10Gth CPU



but use Bluetooth Headphones play with Stereo is low sound

100 volume like 1 volume sound

and play with Hands-free AG Audio is correct sound

100 volume is 100 volume sound

I try ...

1. install windows updates many times
2. use regedit set DisableAbsoluteVolume
   
   0 to 1
3. reinstall Stereo A2DP Driver
4. repairing Bluetooth Headphones

amazing

Stereo Sound is Fixed

100 volume is 100 volume sound

I don't know which is correct solution
