Sound on/off, volume (Windows)

To set sound on/off or volume, click on the speaker icon in the notification area of the taskbar.
Which device
Click on the speaker icon at the left side of the volume knob to toggle sound on/off.

To adjust volume, click on the volume knob and drag the mouse to move it left or right. Once you release the mouse button, the system will sound, so you can use the system sound as a guide of the volume while setting.
