Windows 11 Volume Mixer: route each app to the right speakers

A game goes to headphones while a video uses monitor speakers? Set output and volume for each app in Windows 11, and learn when to change the system default instead.

A desktop PC sends distinct sound-wave paths to headphones on one side and monitor speakers on the other.

If a headset, HDMI monitor and desktop speakers are all connected, sound can land somewhere unexpected. Windows 11 lets apps use the PC’s default output, while Volume mixer can give an individual app its own output and volume. If only one game or browser is going to the wrong place, check its app setting first; change the system default only when you want all default-following apps to move.

Microsoft’s current app-audio guidance confirms that an app can use a different output from the system default. The Volume mixer also has an individual volume control for each listed app.

Choose the setting that matches the problem

  • Every app should move to another device: open Settings → System → Sound and choose the device under Output. This changes Windows’ default playback device.
  • Only one app should use another device: open Volume mixer and change that app’s Output device. Leave the system default alone.
  • One app is too quiet or muted: check its Volume mixer slider and mute state before changing the main Windows volume.
  • The app still ignores the Windows choice: check its own audio or voice settings too, if it provides an output-device selector.

That distinction keeps a one-app fix from changing where other apps play. Windows 11’s enhanced mixer and the Windows + Ctrl + V shortcut were documented in Microsoft’s October 2023 release notes, well before the date on this article.

Route an app through Volume mixer

  1. Connect the destination device. Open Settings → System → Sound and confirm the headphones, speakers or monitor appear under Output. If Windows does not list the device at all, solve that device-detection problem first; an app cannot be routed to an output Windows cannot see.
  2. Open Volume mixer. Go to Settings → System → Sound → Volume mixer, or press Windows + Ctrl + V to get to the sound controls quickly.
  3. Find the app under Apps. Check that its volume slider is not muted or set too low. Then open that app’s Output device list and select the device you want it to use.
  4. Play a short test in that app. Listen at the chosen device, then check any other app you routed. Make one change at a time so you can tell which setting solved the problem.

Use the same steps for each app that needs a different destination. Apps without their own override continue to use the Windows output they follow.

Example: game on a headset, video on speakers

Suppose you want a game in your headset and a browser video through speakers built into a monitor. Set the system Output to your usual speakers, then use Volume mixer to choose the headset for the game and the monitor for the browser. Those are app-specific choices; they do not make either device the default for every other app.

If you later want the game to follow Windows again, select Default in its Output device list if that option is available. You can then change the system Output once and let default-following apps move together.

If the app still uses the wrong output

Check the app’s own audio settings. A game or calling app may have a separate device selection, and Windows’ mixer setting does not replace a choice maintained inside the app. If the app was already open when you changed devices, close and reopen it, then test again.

If the device is missing from Windows’ Output list, follow Microsoft’s guide to a missing or undetected audio output device . If Windows lists the device and only one app still has no sound, use Microsoft’s app-audio troubleshooting guide , which covers per-app volume, output selection and later service or driver checks.

Use the system Output setting for a whole-PC change and Volume mixer for an app-specific exception. That is usually the quickest way to keep a game, video or call on the device you intended.
