To enable Mono audio;
- Open the ‘Ease of Access Settings’ by pressing the Windows logo key + U on the keyboard.
- On the ‘Ease of Access’ settings screen, select ‘Audio’ in the left-hand column.
- You will find the ‘Turn on mono audio’ setting under ‘Audio options’ on the right side of the screen.
- Click or tap the On/Off toggle switch to enable ‘Mono Audio’.
Note: If this does not work it could be because your computer settings are managed by someone else (an IT department or administrator for example). If this is the case you will need to contact them to access these settings or for further help.
