While most computer speakers have a volume control system, it is possible to adjust the system volume through the operating system. Different operating systems have different audio settings.
For a computer running on the Windows operating system, click the Start icon. Once this is done, navigate to the Control Panel. This displays a variety of adjustable settings. Select the Hardware and Sound Settings, and then click on the Audio Devices and Sound tab. This gives you the option to adjust system volume. One can apply this procedure on any Windows version, claims Microsoft.
It is relatively easier to adjust the volume control on a Mac. One simply chooses the Apple menu and then System Preferences. Under System Preferences, select Sound, and then click Output. This is the simplest method to adjust the volume control on any Apple product, according to Apple.
