Fixing EarTrumpet When It Stops Working

Restart the app from the tray

Right-click the EarTrumpet icon in the system tray (you may need to click the small arrow to show hidden icons), choose Exit, then relaunch EarTrumpet from the Start menu. This clears any temporary state without touching your Windows settings.

Restart the Windows Audio service

1. Press Win+R to open the Run dialog.
2. Type services.msc and press Enter.
3. Scroll to Windows Audio, right-click it, and choose Restart.
4. Reopen EarTrumpet and check whether the sliders respond.

Re-check Windows Sound settings

Open Settings > System > Sound and confirm a working output device is selected as default. If the default device changed unexpectedly, EarTrumpet's sliders may appear empty or mismatched with the app you expect.

Confirm app permissions and startup status

In Settings > Apps > Startup, verify EarTrumpet is enabled to launch with Windows. Also check that background permissions for the app have not been restricted, which can prevent the tray icon from updating.

Reinstall as a last resort

If the app remains unresponsive, uninstall it from Settings > Apps, then reinstall from the Microsoft Store or via Chocolatey with choco install eartrumpet.

Check for a known issue

Search the GitHub issue tracker for your symptom; recurring problems after Windows updates are often already reported there with workarounds.

Why EarTrumpet stops responding

EarTrumpet's flyout is essentially a live view into Windows' audio session list, refreshed each time you open it. When that view goes stale or unresponsive, the cause is almost always upstream: the Windows Audio service restarting mid-session, a default device changing while an app is still playing, or a background-app permission that got reset by a system update. None of these require reinstalling Windows or resetting your PC — they're addressed by the ordered checks in this guide.

If you want a side-by-side reference for what a properly working flyout should show compared with the native alternative, see EarTrumpet vs the Windows volume mixer, which walks through the same controls in both tools.

Isolating an app-specific problem

If only one application misbehaves in EarTrumpet while everything else works normally, the issue is more likely with that specific app's audio session than with EarTrumpet or Windows Audio generally. Close and reopen the affected app so it registers a fresh audio session, and check whether the same app behaves normally in the classic Windows volume mixer. If it's broken there too, the app itself — not EarTrumpet — is the source of the problem.

Checking Windows Update history

If the problem started right after your PC restarted for updates, open Settings > Windows Update > Update history to confirm what installed. Audio driver updates bundled into a cumulative update are a common, easily overlooked trigger for EarTrumpet suddenly misbehaving, and knowing the timing helps you decide whether to roll back a driver or simply wait for a fix.

Keeping this timeline in mind also makes it easier to judge whether a symptom belongs on this page or on the more specific Windows 11 or Windows 10 troubleshooting pages, since update-driven issues sometimes differ by Windows version.

Keeping your setup easy to diagnose next time

Once EarTrumpet is working again, it's worth noting which fix resolved it — a service restart, a Sound settings change, or a reinstall — since the same fix is likely to work again if the symptom recurs after a future Windows update. Bookmarking the main troubleshooting hub makes it faster to find that fix a second time.

One more thing to try: a full sign-out

If nothing above resolves it, signing out of Windows entirely (not just locking the screen) and back in forces every background app, including EarTrumpet, to restart cleanly alongside a fresh audio session list, which occasionally clears issues that a simple app restart does not.

Frequently asked questions

Why did EarTrumpet stop working after a Windows update?

Windows updates occasionally reset audio-related services or default devices. Restarting the Windows Audio service and rechecking Sound settings usually resolves this.

Does closing EarTrumpet from Task Manager help?

It can force-close a frozen instance, but exiting from the tray icon is the cleaner first step; use Task Manager only if the tray menu itself is unresponsive.

Can antivirus software interfere with EarTrumpet?

Security software can occasionally block background apps. If EarTrumpet is allowed to run and it still fails, a reinstall is a more direct fix than adjusting antivirus rules.

Is there a way to reset EarTrumpet completely?

Uninstalling and reinstalling it is the practical equivalent of a reset, since it is a lightweight app with no separate database to clear.
