Tired of apps changing your microphone volume without your consent? Of Windows constantly switching to the wrong audio device? Or of losing your device names and icons every time you change USB ports?

Volume Locker is a tray app that locks the volume of your audio devices and switches your audio and communication devices based on priority lists. When you change USB ports, re-pair a Bluetooth device, or update a driver, it transfers your settings, along with the device's name and icon, to the device's new Windows entry. It is a portable, ~2MB binary written in Rust for Windows.

Paste this into Windows PowerShell to install or update:

New-Item -ItemType Directory -Path 'C:\Apps\Volume Locker' -Force >$null; `
  Get-Process | Where-Object { $_.Path -eq 'C:\Apps\Volume Locker\VolumeLocker.exe' } | Stop-Process; `
  curl.exe --progress-bar --location --output 'C:\Apps\Volume Locker\VolumeLocker.exe' `
  'https://github.com/felipecrs/volume-locker/releases/latest/download/VolumeLocker.exe'; `
  Start-Process 'C:\Apps\Volume Locker\VolumeLocker.exe'

Or download the executable from the releases page, place it somewhere like C:\Apps\Volume Locker\VolumeLocker.exe, and run it.

Click the Volume Locker tray icon to open the menu.

1. Open Output devices or Input devices, then select a device.
2. Check Keep volume locked to hold the volume at its current level.
3. Check Keep unmuted to prevent the device from being muted.

Notify on volume restore and Notify on unmute show a notification when Volume Locker acts.

Volume Locker switches your default device to the highest-priority one available.

1. Open Output device priority or Input device priority.
2. Open Device priority settings.
3. Under Add device, select a device, then Add to top or Add to bottom.
4. Select a device in the Priority list to move or remove it.

Communication priority settings works the same way for voice calls and chat apps. By default, it follows the device priority list.

Check Notify on restore in either list to get a notification when Volume Locker switches devices.

To override your priority lists without changing them:

1. Open Temporary priority.
2. Select Output, Input, or the Communication role under either one.
3. Select the device.

It stays active until you uncheck it or restart the app.

Some wireless receivers stay connected while the headset is off or out of range. Volume Locker skips supported headsets in that state, so put a fallback device below the headset in your priority list. See Headset availability.

Windows sometimes treats your device as new when you change USB ports, re-pair it, or update a driver. You would normally lose its custom name and icon, along with anything tied to it.

Volume Locker recognizes the device and transfers its volume lock, unmute lock, priority list entries, name, and icon.

See Settings transfer and Transferring names and icons.

Volume Locker follows the Windows display language, and English is the only language so far. To add yours, see Localization.

Volume Locker started as my first Rust project, born from the dissatisfaction with existing solutions that relied on closed-source tools or lacked specific device locking capabilities. It has since grown to include default device priority management.

I used wolfinabox/Windows-Mic-Volume-Locker for years before deciding to write my own solution.

I was inspired by AntoineGS/teams-status-rs being so amazing in such a lightweight package. I wanted to do something similar, but for volume locking.

Special thanks to:

• Kingloo/volume for the Windows volume control code foundation.
• tauri-apps/tray-icon for the tray icon implementation.
• GitHub Copilot for assisting with the code structure, syntax, and feature implementation.
• @jmb for the great icon design.
