2. Right-click the problematic driver in the Audio inputs and outputs section.
3. Choose Update driver from the context menu.

5. Proceed by following the on-screen instructions and restarting your computer. If the error persists, repeat steps 1-3.
6. Select Let me choose from my computer’s available drivers this time.
7. Pick a driver and install it.
8. Finally, restart your computer and check if the issue is resolved.

Whenever you cannot find the latest driver for your audio device on your computer, you should visit the manufacturer’s website and download it. Follow the steps we just discussed above to install it.

3.2 Rollback the Driver

You can also revert the driver to an older state. Here is how:

1. Follow the steps above to access the Audio and Inputs section.
2. Right-click on the targeted driver and choose Properties from the context menu.
3. Click the Roll Back Driver button in the Properties dialog.
   

   

4. Follow the on-screen instructions to proceed and then check if the issue is resolved.

4. Boot Into Safe Mode

There is also a chance that a background process is causing the problem. To check if this is the case, you can boot Windows into safe mode and try changing the volume from there.

Here is how you can boot in safe mode in Windows:

1. Press Windows + R keys simultaneously on your keyboard to open a Run dialogue box.
2. Enter msconfig in the text field of the dialogue box to open the System Configuration window.
3. Now, head over to the Boot tab.
4. Next, checkmark the box associated with Safe boot, select the Minimal toggle and leave everything else unchecked.
   

   

5. Once done, click Apply and restart your PC to save the changes.
6. Alternatively, press Windows + R keys simultaneously on your keyboard to open a Run dialogue box.
7. Inside the text field of the dialogue box, type cmd and press Ctrl + Shift + Enter together to open up an elevated Command prompt.
8. Once you are inside the Command Prompt window, copy and paste the commands mentioned below. Hit Enter to execute the command.

   bcdedit /set {current} safeboot minimal​

9. Once done, restart your PC to save the changes made.

Now, check if you can change the volume in the safe mode. If you can, then it implies that a background process is a culprit. In that case, you can try performing system restore to revert the system to a previous point in time.
