Fixing EarTrumpet Volume Control Problems

Test the same app in Windows' own mixer

Open the legacy volume mixer by right-clicking the speaker icon in the taskbar and choosing the classic mixer option, or use Settings > System > Sound's app volume section. If the slider there is also unresponsive, the issue is with Windows audio rather than EarTrumpet specifically.

Restart EarTrumpet from the tray

Exit EarTrumpet via its tray icon and reopen it. This refreshes its connection to the current audio sessions, which can resolve sliders that appear frozen.

Restart the Windows Audio service

1. Open Run with Win+R and type services.msc.
2. Find Windows Audio in the list.
3. Right-click and choose Restart.
4. Reopen the app you're trying to control and test the EarTrumpet slider again.

Check for other volume-control apps running

If you have another audio utility running at the same time, such as a hardware control panel or a different mixer app, it may be overriding EarTrumpet's changes. Try closing other audio software temporarily to isolate the conflict.

Check permissions and reinstall

Confirm EarTrumpet has not been restricted by Settings > Apps permissions, then, if the problem persists, uninstall and reinstall from the Microsoft Store or via choco install eartrumpet on Chocolatey.

Search for related reports

Check the GitHub issue tracker for reports describing sliders that don't take effect, especially if it happens with a specific app rather than system-wide.

Why sliders can stop tracking real volume

EarTrumpet's sliders reflect the same per-app volume value Windows stores for each audio session. When a slider looks like it moved but nothing changes, either the app is managing its own internal volume separately from Windows (common in some browsers and games), or another audio utility running at the same time is re-applying its own value right after EarTrumpet sets one. Testing the same app in the built-in mixer, as covered in EarTrumpet vs the Windows volume mixer, is the fastest way to tell which situation you're dealing with.

If the problem is isolated to switching output devices rather than volume itself, see Windows per-app volume for how Windows tracks that setting independently.

Ruling out a stuck audio session

Audio sessions can occasionally get 'stuck' at the Windows level after a crash in the app producing sound. Fully closing the affected app (not just muting it) and reopening it forces Windows to create a fresh session, which EarTrumpet will then pick up correctly on its next flyout refresh.

Checking for exclusive-mode audio conflicts

Some apps and games request exclusive control of an audio device for lower latency, which can temporarily prevent Windows — and therefore EarTrumpet — from adjusting that app's volume while exclusive mode is active. Closing the app fully, rather than minimizing it, releases exclusive mode and lets EarTrumpet's sliders regain control.

You can also review a device's exclusive-mode setting under Sound settings' device properties if this happens repeatedly with the same app.

When to escalate to the issue tracker

If sliders remain unresponsive for a specific, reproducible combination of app and device after trying every step above, that's a good candidate to search for — and if necessary report — on the GitHub issue tracker, including your Windows version and the exact app involved.

Testing after a clean sign-in

Signing out and back in, or restarting the PC, clears any leftover audio session state that a simple app restart may not fully reset, and is worth trying once before concluding the issue requires a reinstall.

Frequently asked questions

Why does an EarTrumpet slider move but the app stays the same volume?

The app may be applying its own internal volume control on top of Windows, or another audio utility could be resetting the level; test the same app in the built-in Windows mixer to confirm.

Can restarting Windows Audio fix stuck sliders?

Yes, in many cases restarting the service clears a stuck audio session that was ignoring volume changes.

Does this happen with all apps or just one?

If it's isolated to one app, the app itself may manage its own volume separately from Windows; if it's every app, focus on the Windows Audio service and default device settings.

Is reinstalling EarTrumpet likely to fix unresponsive sliders?

It can help if the app's own files are corrupted, but first rule out a Windows-level cause using the built-in mixer for comparison.
