Mute one app on Windows 11 and leave every other sound alone

Mute an app silences one program, such as Spotify, Discord or a browser, without touching the master volume. People use it to quiet music when a call starts, or to silence a noisy app while something else keeps playing.

How it works

  • Pick the app and choose mute, unmute, or switch to the opposite of how it is now.
  • It works like the per-app switch in Windows' Volume mixer and covers every place the app plays sound, including each playback device and each browser process.
  • Windows only tracks volume for an app that has played sound since it started, so an app that has stayed silent fails with a clear message instead of guessing.
  • The step reports whether the app ended up muted, so later steps can react to it.

Routines that use it

Quiet music during calls

Start a routine with Mic or camera in use and mute Spotify, then unmute it again when the call ends.

Silence a game in the background

When you switch away with the App focused trigger, mute the game you left so only the app you are using makes noise.

One key for the browser

Bind a Hotkey to Mute an app set to switch, so one press silences or brings back your browser's audio.

Good to know

  • The app must have played sound since it started; a routine can open it and wait a moment before muting.
  • Store apps need their program picked rather than only their store entry.

Questions

How do I mute just one app on Windows 11?
Add Mute an app to a routine and pick the program. It flips the same per-app mute that the Volume mixer shows, so the rest of your sound is untouched.
Why does it say the app isn't playing sound?
Windows only creates a volume control for an app after it plays something. Play a sound in the app first, or let the routine open the app and wait a few seconds before this step.
