Most of the time the meeting app is using the wrong microphone, or Windows privacy settings are blocking it. Choose the correct mic in the app's audio settings and check Settings > Privacy & security > Microphone.
Common causes
Wrong device selected
Teams or Zoom may be using the laptop mic, the monitor, or a disconnected headset.
Privacy settings block access
Windows can block apps from using the microphone.
Muted in hardware
Headsets and some keyboards have mute buttons that override the app.
Bluetooth headset in the wrong mode
Bluetooth headsets switch between listening and call modes, and can connect without the mic.
Driver or dock issues
Audio drivers and docks can cause the mic to disappear.
How to fix it, step by step

In Teams or Zoom settings, choose the correct microphone and use the test feature.
- 2
Check privacy settings
Turn on microphone access for apps and desktop apps in Windows privacy settings.
- 3
Check physical mute
Look for a mute switch on the headset cable or a lit mute key on the keyboard.

Reconnect the headset
Unplug and reconnect, or remove and re-pair Bluetooth headsets.
- 5
Check Windows sound settings
Make sure the mic isn't disabled and its level is up in Settings > System > Sound.
When to call a technician
If microphones fail across the office, it's often a driver or dock problem. We standardize headsets and audio settings so meetings just work.

Frequently asked questions
Why can people hear me in Zoom but not Teams?
Each app has its own device setting. Teams may be pointed at a different microphone.
Are wired headsets better than Bluetooth for calls?
Wired or USB-dongle headsets are usually more reliable for calls than standard Bluetooth.
Why does my Bluetooth headset sound worse on calls?
Standard Bluetooth lowers audio quality when the mic is in use. A headset with its own USB dongle avoids this.
