Hello Lenny,
To better assist you with your concern, I'd like to know the following:
- Confirm which build is currently installed on your device. To check, follow the steps below:
- Press Windows key + R, then type in winver.
- Click OK
- What is the make and model of your computer?
- Are you using a laptop keyboard or external keyboard?
Adjusting the volume levels using the keyboard shortcuts depends if your device/keyboard supports media keys.
Meanwhile, let's try creating a shortcut key for the Master Volume. Refer to the steps below:
- Right-click on an empty area on Desktop, then select New and Shortcut.
- Copy and paste the location below:
C:\Windows\System32\SndVol.exe -T 76611119 0
- Click on Next button and provide a name for the said Shortcut and click Finish.
- Right-click on it and select Properties.
- Assigned your desired shortcut key like F11 or F10 by just pressing it in the Shortcut key area.
- Click Apply and Click OK to save changes.
Looking forward to your response.
Regards.
