Volume Control Limitations

Due to macOS limitations with multi-output devices, changing the system volume while using may not work as expected. This is a known limitation of macOS that affects virtual audio devices.

​
Using Tail’s Built-in Volume Control

To address this limitation, we’ve implemented a dedicated volume control feature directly within the Tails desktop application.

Troubleshooting

If you’re experiencing issues with volume control:
  1. Ensure “Nutshell Speaker” is selected as your output device
  2. Deselect “Nutshell Speaker” in your system settings, choose your desired output device, and verify you can hear audio
  3. Try restarting the application if volume control is unresponsive
If you need to use system-wide volume control, you’ll need to switch back to your default audio output device.
