What Prevents the Volume Mixer from Opening on Windows?

We felt that it was important for you to know the reasons due to which the volume mixer might not be opening on your computer before you went forward with implementing the solutions.

  • Hardware and Sound Glitch: It is possible in some cases that the hardware and sound features on Windows have been glitched due to a misconfiguration inside settings or due to any other bug that has affected your operating system. Therefore, it is recommended to perform a complete troubleshoot on this and check if doing so fixes the volume mixer won’t open issue.
  • Disabled Audio Service: If your volume mixer isn’t opening, it can also mean that you or an application on your computer might have disabled the Audio service from the service manager window. This setting can easily be changed to get back the volume mixer feature by following the guide below.
  • Exclusive Control: If you have granted the exclusive control of your audio drivers to a particular application, it might be disabling it to conserve power or for any other reason and this can also prevent the volume mixer from launching. Therefore, it is always recommended to refrain from granting the exclusive control of the driver.
  • Sound Drivers: It is also vital in some cases that the audio driver has been updated to the latest available version and that it actually matches the hardware recommendation of your computer. If that is not the case, then this issue is commonly seen on Windows.
  • Antivirus Software: Some Antiviruses are also known not to play well with the latest Windows operating systems and they prevent the computer from functioning properly in some cases which can also end up affecting the volume mixer.
  • Taskbar Notifications: If you have disabled the taskbar notifications on your computer, the volume mixer might not open up sometimes because this feature needs to be enabled and if it isn’t, in some versions of Windows, the Volume mixer gets glitched out.
