In the list of services, look for "Windows Audio". Open the services: Press the keys Win + R, enter services.msc and hit Enter.If so, try disabling the "Quick Start" function. Check if the volume mixer starts working after a simple reboot (ie via "Restart", not "Shutdown") of the computer.If it still does not appear, the reason may be: opening the mixer on another screen (if more than one monitor is connected) or off screen.

If nothing happens when you manually start the volume mixer, check in the Task Manager if the sndvol.exe process is hanging there - if it is there, in the Details tab, try to delete the task and then open the volume mixer again.If the window opens and works, try opening the volume mixer using the standard method, and if it doesn't work, use the methods described below.If a window opens but shows "No audio devices installed," use the driver installation methods in the above-mentioned instruction on sound not working. Check if the volume mixer opens when pressing the keys Win + R (Win is the key with the Windows logo), enter sndvol and hit Enter.
