Teams: they cannot hear me, or I hear nothing
In our experience Teams usually picked the wrong audio device after a Windows update or a new headset.
Try this first
- 1In Teams click the three dots next to your profile picture > Device settings. Confirm "Speaker" and "Microphone" are set to the right headset.
- 2Run "Make a test call" on the same screen. It plays your recording back so you know whether the mic actually works.
- 3If the test call captures nothing: Windows Settings > Sound > Input device properties > volume 75-100%, and confirm "Mute" is not on.
- 4Bluetooth headset? Unpair and re-pair. Bluetooth and Teams hate each other after a sleep cycle.
When to bring us in
Does it work in Zoom or Google Meet with the same headset? Then it is Teams-specific: a policy or admin setting may be blocking access.
