STRAIGHT TO THE SOLUTION

Test the microphone in Windows Sound. Check desktop-app access and the headset mute switch.

Review input, voice volume and push-to-talk binding in the game. Check for a muted group.

Restart after a device change and test with a teammate. Record whether sending, receiving or both fail.

Why does ordinary game audio work?

Playing effects and recording voice use separate audio paths.
