How to enable Mono Audio in Windows 10

Modern day electronic devices such as PCs and movie players allow users to readily switch the audio channel between stereo and mono in an instant. That said, a majority of us aren’t even aware of the difference between the two, i.e., Mono Audio and Stereo audio.

We’ll learn about this and also see the method of enabling Mono Audio output in Windows 10. It is very apparent that every individual will have his or her own interpretation of the terms ‘mono’ and ‘stereo’, influenced by their own experiences and expectations. At the very basic level, Stereo means a sound system that comes from more than one source and is directed through two or more speakers which surround the listener. It induces a spatial magic by creating the illusion that you are in the middle of a three-dimensional sound source.

On the other hand, mono audio has only one spatial dimension; something that can be either close to (loud) or far away (quiet) from the listener. People or individuals with hearing impairment find Mono audio useful. As such, with accessibility options directly built into OS, users who may have trouble using their computers normally can get a little more functionality out of their favorite OS. Windows 10 Creators Update features the mono audio option. It is built right into the Settings.

Click the Windows Start button and select the “Settings” icon. Next, choose the “Ease of Access” tile visible under the Settings window.

Now, click “Other options” in the sidebar and scroll down to the bottom of the window. There, you’ll find “Mono audio” option displayed in Audio menu. Set it to “On”.

Alternatively, you can enable the same feature via a registry tweak. Follow the instructions given below.

Open the Registry Editor and navigate to the following address-


In the right side you will see a 32-Bit DWORD value AccessibilityMonoMixState. Double-click on it and give it a value of 1 to enable it.

The values are:

  • 0 – Off
  • 1 – On.

If this DWORD does not exist, you will have to create it.

Hope this helps!
