Setting Individual App Volume in Windows
Sometimes the goal isn't a full mixer overview, just fixing one app's volume, like a browser that's too loud compared to everything else. Windows lets you target a single app's level directly.
This page focuses on that narrower task: finding, changing, and saving the volume for one specific application.
Finding one app in the mixer
Open the Volume Mixer (right-click the tray speaker icon, choose "Open Volume mixer"). Apps are listed by name if they've played audio recently; scroll to find the one you want and adjust only its slider.
If the app isn't listed
- Play any sound in the app so Windows registers it as an active audio source
- Check that the app isn't set to a different output device than the one you're viewing
- Restart the app if it was already open before you launched the mixer
Keeping the level from resetting
Some apps reset their own internal volume on launch, which is separate from the Windows-level slider; check the app's own audio settings if the level keeps jumping back up.
Using search instead of scrolling
On Windows 11, the Volume mixer page in Settings supports the same search box used elsewhere in Settings; typing an app's name in the Settings search bar and choosing "Volume mixer" narrows the results faster than scrolling a long app list by hand, especially on a PC with many background processes running.
Isolating one app's audio for testing
To confirm you're adjusting the right app, mute every other running app temporarily and play sound only from the one you're checking. This is a quick way to verify that a persistent noise, like a notification chime, is really coming from the app you suspect rather than a different one sharing similar audio cues.
Faster single-app adjustments
EarTrumpet shows all running apps as sliders in one flyout, so finding and nudging one app takes a single click instead of navigating a settings page each time.
When individual control isn't enough
If one app still sounds too loud or too quiet after maxing or minimizing its Windows-level slider, check the app's own internal volume or audio settings, since many media players, browsers, and games apply their own gain on top of whatever Windows sends them. For a broader look at how these layers stack, see Windows audio control and the Windows app volume mixer.
Frequently asked questions
Can I set a volume limit for one app permanently?
Windows doesn't offer a hard cap, but the last slider position is generally remembered per app and device.
Why does one app sound loud even at a low slider setting?
The app may boost its own internal volume separately from Windows; check its in-app audio settings too.
Can I set individual app volume higher than 100%?
No, the Windows mixer slider caps at 100% of the app's own output; boosting beyond that requires the app's own audio settings, if it offers one.
Why does an app show two entries in the mixer?
Some apps run multiple processes that each produce audio, such as a browser with several tabs playing sound, so each process can appear as a separate mixer entry.
