The Windows Volume Mixer Explained
The Volume Mixer is the Windows tool for setting a different volume level for each running app. It has existed since Windows 7 in one form or another, and its location has changed across Windows 10 and Windows 11.
This page explains how to open it on each version, what it shows, and what to do if it stops working correctly.
Opening the Volume Mixer on Windows 11
- Right-click the speaker icon in the system tray
- Select "Open Volume mixer"
- Or press Win+Ctrl+V to jump straight to it
- Adjust each app's slider independently
Opening the Volume Mixer on Windows 10
Windows 10 doesn't have the same dedicated page; instead, right-click the speaker icon and choose "Open Volume mixer" for the classic sndvol-style view, or go to Settings > System > Sound > App volume and device preferences. See the Windows 10 volume mixer guide for screenshots-free step-by-step instructions.
What the mixer controls
- Individual volume for each app producing sound
- Master volume for the system and the current device
- In Windows 11, the output device an app is using
Volume Mixer vs. plain volume control
It's easy to confuse the Volume Mixer with basic Windows volume control: the flyout's single slider changes the master level for the whole system, while the mixer breaks that level down per running app. Adjusting the mixer never changes the master slider itself, though the two multiply together to produce what you actually hear.
The mixer also remembers a last-used volume per app and per output device, so an app that sounded quiet on speakers may play louder the first time you switch to a headset, since it's recalling a different saved level.
Renaming the tool across Windows history
Windows Vista and 7 introduced the mixer as a standalone popup (sndvol.exe) with vertical sliders. Windows 8 and 10 kept that same popup for per-app control but added a parallel "App volume and device preferences" page in Settings. Windows 11 folded both into a single Volume mixer page, though the old popup still launches if you type sndvol directly.
When the mixer won't open or respond
A mixer that won't launch or shows a blank window is often tied to the Windows Audio or Windows Audio Endpoint Builder service failing to run. See how to fix the Windows Volume Mixer for the exact restart steps.
A quicker alternative
EarTrumpet puts the same per-app sliders directly in a tray flyout, so you don't need to right-click and navigate a settings page each time. It's a lightweight, free alternative described on the EarTrumpet alternatives page alongside the built-in mixer.
Tips for a cleaner mixer view
- Close background apps that produce sound but aren't in use, so the mixer list stays short
- Give each connected device a clear name in Windows audio control settings so the per-app device dropdown is easy to read
- Check the mixer immediately after installing a new app, since it won't appear until it plays audio once
Frequently asked questions
Is the Volume Mixer the same on every Windows version?
No. Windows 11 has a redesigned mixer in Settings; Windows 10 uses a classic popup window or the App volume preferences page.
Can I pin the Volume Mixer somewhere for quick access?
You can pin sndvol.exe or the Settings page to Start, but a tray-based app like EarTrumpet is generally faster.
Does the Volume Mixer control microphone levels too?
No, the Volume Mixer only shows playback (output) volume; microphone input levels are set separately under Sound settings' input device section.
Can I reorder apps in the Volume Mixer?
No, Windows lists apps in the order they started producing audio and doesn't offer manual reordering or pinning.
