Follow these checks in Audio Fix →

When this guide applies

Exact WF-C710N. No reset or deletion; output routing is an observation, not proof of a defective microphone. Computer with an established Classic Bluetooth calling connection. This checks app routing, not missing drivers, permissions or LE Audio configuration.

Connection scope: Bluetooth. Symptom: My microphone isn’t working.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at computer. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

computer

Is this a computer using the documented Classic Bluetooth calling connection?

Confirm HFP/HSP call support and the visible headset call input. Do not substitute an A2DP music-only connection or assume LE Audio uses these endpoint names.

Look for: Choose only what you can confirm.

Does the app now show the headset input and detect your voice?

Observe its available input indication without placing an unsolicited call. A selection alone is not proof that another participant can hear you.
