On Windows 10, you can adjust the volume of your device quite easily. You can do this by using the speaker icon in the notification area, using the volume buttons at the side of your device, and you can even ask Cortana to control the audio.
However, using these options you’re only adjusting the “master volume”. If you want to adjust the system or a particular app’s sounds, the steps are different.
In the past, you would just use the Volume Mixer experience, but starting with Windows 10 April 2018 Update (version 1803), the advanced sound settings are integrated into the Settings app.
To change the sound settings for an app, launch the app, and then do the following:
Click on System.
Click on Sound.
Under “Other sound options,” click the App volume and device preferences option.
Under “App,” adjust the volume level for the app you want. Or you can also adjust the volume level for system sounds.
Once you completed the steps, the app will use the same sound level in relationship to the master volume.
It’s worth noting that within the App volume and device preference page, you can also change input and output source for your system and apps individually, and you can always press the Reset button to return to the default settings.
Alternatively, you can also right-click the speaker icon from the notification area and use the Volume Mixer to perform the same task, but the Settings app is the recommended method as eventually the Control Panel will fade out completely from Windows 10.
If you don’t see the sound settings, it’s likely because you’re not running Windows 10 version 1803 (April 2018 Update).
