When talking about VLC Player, by default the program is configured not to listen to the multimedia keys (especially the volume keys) that your keyboard may have. As a result, every time you press volume up or volume down key on the keyboard, the system volume (which affects the entire computer system globally including the volume of the VLC Player) is increased or decreased respectively.
Since VLC Player is a versatile application, the program also allows you to map the volume buttons available on your multimedia keyboard with itself. When the buttons are mapped, the volume of the VLC Player can be controlled right from the keyboard itself, provided the program is running and is active on the screen. If the case is otherwise, the system volume is controlled with the buttons. This means that after you map the buttons with the VLC Player, the buttons act dynamically and automatically switch between the VLC Player and the system wherever required.
Below are the instructions that would guide you through the process of configuring your instance of VLC Player the way it is described above:
- Log on to the computer using the account in which you are experiencing the problem while using the VLC Player.
- Initialize the VLC Player by double-clicking its icon, or by opening any audio or video file in the application.
- Once opened, go to the Tools menu from the menu bar.
- From the displayed list, go to Preferences.
- On the opened Preferences box, from the left pane, click to select Hotkeys category.
- From the bottom of the right pane, uncheck the Ignore keyboard volume buttons checkbox.
- Once done, click Save to save the changes.
- Restart the VLC Player to allow the changes to take effect.
- If the modified settings do not work, restart the computer and then try again.
