• Check for available firmware updates via the FiiO Control app or FiiO's official website. Firmware updates can resolve compatibility and performance issues.

App Connectivity Issues:

• Ensure Bluetooth is enabled on your source device if the app requires it for communication (though the JA11 is a wired DAC, some companion apps might use Bluetooth for control).
• Restart the FiiO Control app and your source device.
• Reinstall the FiiO Control app.
• Verify that your device's operating system is compatible with the app.

Microphone Not Working:

• Confirm your headphones have a working in-line microphone.
