How to Manage App Audio on Windows

Open the central place for app audio

1. Right-click the speaker icon in the taskbar and choose 'Sound settings' or open the Volume mixer with Win+Ctrl+V.
2. Look at the 'Apps' section, which lists every app that has recently played sound.
3. Each app row shows a volume slider, a mute button, and an output device dropdown.

Mute a single app

1. Open the Volume mixer as above.
2. Click the speaker icon next to the app's name to mute it.
3. Click it again to unmute — the previous volume level is remembered.

Check microphone use per app

1. Open Settings > Privacy & security > Microphone.
2. Scroll to 'Let apps access your microphone' and review the list of recently active apps.
3. Toggle off access for any app you don't want using the microphone.

Managing app audio with EarTrumpet

EarTrumpet consolidates volume, mute, and output-device controls for every app into one flyout, so you're not switching between the mixer and Settings to manage the same apps.

What you need before you begin

Everything here uses tools already included in Windows 10 and Windows 11 — no download is required for the volume, mute, or microphone-permission steps. You'll need each app open and producing sound to see it in the mixer, and you'll need standard user permissions (not admin) to change microphone access, since that's a per-account privacy setting rather than a system-wide one.

Alternative: manage everything from one flyout with EarTrumpet

Instead of switching between the Volume mixer and the Privacy & security settings page, EarTrumpet puts per-app volume, mute, and output-device controls in a single flyout that opens from the tray icon. It doesn't manage microphone permissions — that stays in Settings — but it does consolidate the audio-specific controls covered in the first two sections above into fewer clicks.

When app audio management doesn't behave as expected

If muting an app in the mixer doesn't actually silence it, confirm the app isn't also playing through a different device than the one you expect — check its output dropdown in the same mixer row. If an app keeps reappearing in the microphone access list after you've turned it off, it may be requesting access again each time it launches; toggling it off is a per-session setting in some Windows builds rather than permanent.

For a narrower fix-it sequence when one app's slider specifically won't respond, see how to fix app volume that won't change. For step-by-step device switching rather than app-level control, see how to switch audio output.

Frequently asked questions

Can I stop an app from playing sound entirely?

Muting it in the Volume mixer stops audio without closing the app, which is usually simpler than digging into the app's own settings.

Does Windows show which app is using the most audio resources?

No, Windows doesn't report per-app CPU or bandwidth use for audio; the mixer only shows volume level and mute state.

Is there a way to see app audio history?

Windows doesn't keep a history log of app audio activity; the mixer only reflects apps that are currently or very recently active.

Can I block an app from playing audio entirely, not just mute it?

Muting via the Volume mixer is the closest built-in option; it silences output without closing the app or needing separate permissions.

Does managing app audio also cover in-game voice chat volume?

Yes, as long as the game or chat client uses the standard Windows audio session, its voice channel appears in the mixer like any other app; some games route voice through a separate overlay process with its own entry.

Is microphone access the same setting as microphone volume?

No — access (Settings > Privacy & security > Microphone) controls whether an app can use the mic at all, while volume/input level is a separate slider in Settings > System > Sound.
