Lingo N21 – Microphone Not Working

If people cannot hear you during a call or meeting, follow these steps.

Step 1 – Make Sure the Microphone Is Not Muted

Check the Mute / Microphone control on your Lingo N21. Make sure the microphone is unmuted, then test it again.

Using a Computer?

Step 2 – Select Lingo N21 as the Microphone

Open your computer’s Settings → Sound.

Output / Speaker → Avantalk Lingo N21

Input / Microphone → Avantalk Lingo N21

If you see both Stereo and Hands-Free, use Hands-Free for calls.

Step 3 – Check Your Calling App

In Zoom, Teams, Discord, or another calling app, open Audio Settings.

Speaker → Avantalk Lingo N21

Microphone → Avantalk Lingo N21

Use the app’s microphone test if available. The app may use different audio settings from your computer.

Using a Phone?

During the call, tap the Audio / Bluetooth button on the call screen.

Select Lingo N21.

If Phone, Speaker, or another Bluetooth device is selected, the Lingo N21 microphone will not be used.

Something Doesn’t Look Right?

I Can Hear the Call, but They Cannot Hear Me

First make sure the Lingo N21 microphone is not muted. Then check that your computer or calling app has Microphone → Avantalk Lingo N21.

Lingo N21 Is Not Listed as a Microphone

Make sure the headset is connected by Bluetooth. If it is connected but still not listed, disconnect it, reconnect it, then open Sound settings again.

Microphone Works in One App but Not Another

Open the app where the microphone does not work. In its Audio Settings, select Microphone → Avantalk Lingo N21. The app may be using your computer’s built-in microphone instead.

Microphone Still Does Not Work

Test the Lingo N21 with a phone call or another calling app. If it works there, check the original app’s microphone settings or permissions. If it does not work anywhere, contact Avantree Support.
