Every Volume Setting in Windows, Explained
"Volume settings" can mean several different things in Windows depending on whether you're adjusting the whole system, one app, or one device. This page separates each type and shows exactly where to change it.
It's a companion to the broader Sound settings walkthrough, focused specifically on volume levels.
Master (system) volume
Set from the taskbar flyout, keyboard media keys, or the slider at the top of Settings > System > Sound. This affects the overall loudness of the currently selected output device.
Per-app volume settings
Each running app has its own slider inside the Volume Mixer, layered on top of master volume. See Windows per-app volume for the full explanation.
Per-device volume
Some devices, especially USB headsets or docks, expose their own volume level independent of Windows's master slider. This is set in the device's own hardware control (buttons or companion software) rather than in Windows.
Notification and communication volume
Windows offers a separate "Communications" behavior under Settings > System > Sound > More sound settings, on the Communications tab, which can automatically lower other apps' volume when a call is detected. This sits on top of the app and master levels described above and only kicks in during detected voice calls.
Volume settings for accessibility
Windows Ease of Access settings include options like mono audio, which combines left and right channels into both ears, useful for anyone with hearing loss in one ear. These accessibility-related audio options live separately from the main volume sliders but affect how the same volume settings are ultimately reproduced.
System sound volume
Notification and system sounds (like the "ding" on errors) generally follow the same master volume, but some apps let you separately mute notification sounds inside their own settings.
Resetting volume settings
If levels seem inconsistent across apps, resetting each app's slider to 100% in the mixer and then adjusting master volume gives a clean, predictable starting point.
Where to adjust volume day to day
- Fastest: taskbar flyout or keyboard media keys for master volume
- Most precise: the app volume mixer for individual app levels
- Most complete: Windows volume control overview if you're unsure which layer applies
- For device-specific quirks, check the device's own hardware controls or companion app first
Frequently asked questions
Why is my volume different for the same app on two devices?
Windows can remember separate volume levels per app-and-device pair, so switching headsets can bring back a different saved level.
Does Windows have a volume normalization feature?
Windows doesn't apply cross-app loudness normalization by default; some individual apps or audio drivers offer their own normalization option.
Why does a call automatically lower my music volume?
That's the Communications setting under Sound settings, which can duck other audio automatically when it detects a call; it can be turned off if unwanted.
Is there a separate volume setting for alarms and reminders?
Alarms and reminders generally use the same master and system-sound volume as everything else; Windows doesn't offer an independent alarm volume slider.
