Match the symptom before changing settings
| What you observe | Where to focus |
|---|---|
| Only one browser tab is silent | Check the tab, site and browser audio controls. |
| App appears in mixer at zero | Raise or reset its stored volume. |
| App is routed to an old monitor | Change its per-app output to Default or the correct device. |
| Fresh Windows account works | The app's profile or user settings may be corrupted. |
Diagnose app-specific sound repair without guessing
Confirm Windows and another app can play sound normally, then keep diagnosis inside the affected app. Check the app's output selection, per-app volume, mute state, and exclusive/audio settings.
Next, change one variable at a time. Try a known-good speaker, headset, microphone, cable or Bluetooth accessory when one is available, and test the affected device on another port or computer. A second device working on the same Windows PC points toward the original hardware or connection. The original device working elsewhere points back toward this PC's routing, permissions, services or driver. Keep USB hubs, docks, monitors and audio interfaces in mind because each can create an additional playback or recording endpoint.
Use the symptom evidence to choose the next layer: “Only one browser tab is silent” suggests check the tab, site and browser audio controls., while “App appears in mixer at zero” points toward raise or reset its stored volume.. Do not install random driver packages or registry files from download sites. Record the device name, the exact error, when the problem began and whether a Windows, driver, app or hardware change happened immediately before it. That record makes rollback, manufacturer support or repair far more precise.
Because other apps already produce sound, hardware failure is unlikely. Only move to device testing if the affected app also exposes device errors or the problem spreads to other applications.
Correct the app's stored volume and output
Start the affected app and play media so it appears in Settings > System > Sound > Volume mixer. Confirm it is not muted, raise its volume and select the correct Output device. Reset sound devices and volumes for all apps to recommended defaults if the stored route is unclear.
Open the app's own audio settings. Games, editors, streaming tools and meeting software may choose a different output from Windows. Set the device explicitly for the test, then fully close and reopen the app.
1Compare with another app
- Play a Windows test tone or local file.
- If other apps work, keep the repair scoped to the silent app.
- If everything is silent, use the general no-sound guide instead.
2Check browser-specific controls
- Unmute the tab and verify the site is allowed to play sound.
- Disable one extension at a time in a private test window.
- Clear only the affected site's permissions before resetting the entire browser.
Repair or reset the application
For Store apps, open Settings > Apps > Installed apps > the app > Advanced options. Use Repair first because it preserves data; use Reset only after understanding what local settings may be removed. Traditional desktop programs may provide Repair in Installed apps or their installer.
Update the app and Windows, then inspect any exclusive-mode, surround or audio-engine setting inside the program. Communication apps may independently select speakers and microphones. Media players may use passthrough formats unsupported by the selected device.
1Clear temporary conflicts
- Close other apps that may hold the device exclusively.
- Restart Windows Audio services if the app remains stuck.
- Restart Windows and test before reinstalling.
2Reinstall with data awareness
- Back up projects, presets and account-specific local data.
- Uninstall the affected app, restart and install from its official source.
- Restore settings gradually so a broken profile is not imported immediately.
Treat protected media and remote sessions separately
Streaming services can fail because of browser DRM, output protection or an unsupported HDMI path even when ordinary videos play. Test another supported browser, disable screen-recording tools and connect the display directly. Do not use DRM-bypass utilities.
Remote Desktop, virtual machines and streaming software create virtual audio endpoints. Confirm whether audio should play on the local or remote machine and review the session's redirection settings. A virtual output left behind after the session can also capture later app audio.
Verify the repair before making more changes
Play the same content in the affected app, close and reopen it, then restart Windows. Confirm the app continues using the intended output at normal volume.
Keep the app-specific setting or permission that restores sound and avoid system-wide repairs once the scope is proven local.

Frequently asked questions
Why is Chrome silent but Windows sounds work?
Chrome or the site may be muted, routed to another output or affected by an extension or site permission.
What does Reset sound devices and volumes do?
It returns per-app volume and output choices to recommended defaults; it does not erase personal files.
Should I reinstall my audio driver for one silent app?
Usually not first. Working system sounds prove the device and basic driver path function.
