Take Control of Every App’s Sound
Windows 11 includes built-in per-app audio controls that let you lower a noisy browser tab, raise a meeting app, mute a game launcher, or route individual programs to different playback devices. This guide explains how to use Volume Mixer from Settings and the taskbar, how to assign input and output devices per application, and why an app must be producing sound before it appears. It also covers useful daily setups, troubleshooting steps for missing apps or ignored settings, and the limits of Windows audio routing. With a few adjustments, you can keep calls clear, media at a comfortable level, and background notifications from interrupting your work.
Windows 11 can control sound on an app-by-app basis, so you do not have to accept one master volume level for everything. You can turn down a web browser while keeping a video call easy to hear, mute a game launcher without muting the game itself, or send selected apps to a headset while the rest of the system plays through speakers. The key tool is Windows 11’s Volume mixer, available in Sound settings and through the taskbar.
What per-app volume control can do
The master volume affects all audio played through the current Windows output device. Per-app controls sit underneath that master level. Each program can have its own slider, mute setting, and, in many cases, a preferred output and input device.
This is especially useful when several audio sources compete for attention. Common examples include:
- Lowering music or a browser video while keeping Microsoft Teams, Zoom, or another call app prominent.
- Muting notification-heavy apps during a presentation or gaming session.
- Sending a meeting app to a USB headset while music continues through desktop speakers.
- Selecting a dedicated microphone for a recording or communication app.
- Reducing a game’s volume without changing Windows system sounds.
Windows normally remembers a program’s volume preference. However, the app must be open and actively playing or recording audio before it can appear in the mixer.
Open Volume mixer in Windows 11
The full mixer is in the Settings app. Right-click the speaker icon in the notification area on the right side of the taskbar, then select Volume mixer. You can also open it manually by going to Start > Settings > System > Sound > Volume mixer.
At the top of the page, Windows shows overall output settings. Below that, the Apps section lists programs with active audio sessions. Each listed app has a volume slider and a speaker button for muting.
- Start the app you want to adjust and play audio in it.
- Open Settings > System > Sound > Volume mixer.
- Find the app under Apps.
- Drag its slider left to reduce volume or right to increase it.
- Select the speaker icon beside the slider to mute or unmute that app.
- Leave the master volume at a safe, comfortable level and fine-tune individual apps below it.
For a quick global adjustment, click the taskbar speaker icon and move the main volume slider. That fast panel is useful for overall loudness, while the Settings page provides the detailed per-app controls.
Choose a separate output or input device for an app
Windows 11 may allow an individual application to use a different playback device from the system default. In Volume mixer, select the app’s row or expand its options, then look for Output device. Choose the available device you want, such as Speakers, Headphones, a USB headset, or an HDMI display.
For apps that capture sound, you may also see an Input device option. This can be helpful if you have a webcam microphone, a USB microphone, and a headset microphone connected at the same time.
| Goal | Windows 11 setting | Practical example |
|---|---|---|
| Make one app quieter | Apps > app volume slider | Set a browser playing music to 25% while a call remains at 80%. |
| Silence a distracting app | Apps > speaker mute button | Mute a game launcher but keep the game’s audio enabled. |
| Send audio to a headset | App options > Output device | Route a video meeting to a USB headset instead of room speakers. |
| Use a specific microphone | App options > Input device | Select a USB microphone for a recording app. |
| Return to normal behavior | Reset under Volume mixer | Remove custom app volumes and device assignments. |
Build a practical audio setup
A useful setup starts with the default device. Go to Settings > System > Sound and select the output device that should handle most audio. Then use Volume mixer only for exceptions. This prevents unnecessary routing rules and makes troubleshooting easier.
For work and calls
Set your call application to a moderately high app volume, but avoid pushing the Windows master volume to its maximum. If possible, assign the call app to a headset and select its microphone explicitly. Keep browsers, music players, and chat notifications lower so they do not mask speech.
For gaming and streaming
Keep game audio on your preferred speakers or headset, reduce launchers and browser audio, and mute apps that produce frequent alerts. If you stream or record, review your recording software’s own audio settings as well. Windows routing determines where an app plays, but capture software can use independent sources and mixes.
Per-app volume is relative to the Windows master volume and the app’s internal volume control. If an app is quiet at every slider position, check the app’s own settings and the physical volume control on your speakers or headset.
Why an app does not appear in the mixer
The Apps list is not a permanent catalog of every installed program. Windows displays audio sessions, which generally means an app has recently produced sound or is currently using an audio device. Open the program, begin playback, then return to Volume mixer.
If it still does not appear, work through these checks:
- Confirm the correct output device is selected under Settings > System > Sound.
- Verify that the app is not muted within its own settings.
- Check whether the app is paused, disconnected from a call, or playing to a browser tab that has been muted.
- Disconnect and reconnect USB, Bluetooth, or HDMI audio hardware, then test again.
- Install current audio drivers through Windows Update or your PC manufacturer’s support resources.
- Close and reopen the app after changing devices; some older programs only read the device selection at launch.
Fix settings that are ignored or sound routed incorrectly
Applications do not all handle Windows device changes in the same way. Communication, recording, and game applications often provide their own speaker and microphone menus. When an app’s internal choice conflicts with the Windows mixer selection, the app’s own audio settings may take precedence. Select the desired device inside the app, then confirm the result in Volume mixer.
If you need to clear custom assignments, open Settings > System > Sound > Volume mixer and use Reset in the Reset section. This restores recommended defaults for app volumes and devices. You will need to recreate any intentional routing afterward.
Also check the classic sound controls when a device is missing entirely. In Sound settings, use the available option to open more sound settings, then confirm that the playback or recording device is enabled. A disabled device cannot be selected for an individual app.
Limits of Windows 11’s built-in mixer
The built-in controls are ideal for common volume balancing and simple device assignments, but they are not a full audio-production router. Availability of per-app output or input choices can vary with drivers, connected hardware, and how an application uses audio. Bluetooth headsets may expose separate stereo and hands-free profiles, for example, which can change sound quality or microphone behavior during calls.
For most users, the reliable approach is simple: choose one default output device, adjust active apps in Volume mixer, and create individual routing rules only where they solve a clear problem. Reset the mixer if an old device or forgotten app preference starts causing confusion.
