The old Volume Control from Windows XP was replaced in Windows Vista, 7 and 8 by the Volume Mixer. The new application brings to Windows much more flexibility regarding the sound management of the different applications you have installed on your PC. In Windows XP the only feature of the Volume Control was to increase or decrease the general system sound level. In Windows Vista, 7 and windows 8, the Volume Mixer is capable of managing sound settings for each multimedia application installed on your PC.
To access the Volume Mixer you have to click on the small volume icon from your taskbar.
To access the volume mixer in Windows 10, click the small search icon (magnifying glass) in the bottom-left corner of the screen and search for “adjust system volume”.
At this point the Volume Mixer looks almost the same as in Windows XP. Here you can increase or decrease the sound level of your system. If you want to make individual application settings, click on the Mixer link.
As you can see in the below screenshot, the Volume Mixer will load a list of all the running multimedia applications.
To configure the sound settings for each application move the level up or down. To mute/unmute an application, just click on the speaker button beneath it.
