Microsoft Teams Microphone Not Working? Start With These Checks
If colleagues can see you in Microsoft Teams but cannot hear you, start with the microphone path before changing the network. A muted headset, a different selected input, or a permission setting can look like a larger problem.
This guide is for small-business staff and remote workers. Change one thing at a time and test again. Menu names vary by Teams version, operating system, and organization policy.
1. Check both mute controls
Look at the meeting's mute control and the physical button on your headset or microphone. Some headsets mute when the boom is raised. Confirm the device is connected and positioned for normal speech.
If you cannot hear other people, check the speaker path instead. If others hear robotic or broken audio rather than silence, record that symptom separately.
2. Select the microphone you intend to use
In the Teams desktop app, open Settings and look under Devices for the microphone selection. A laptop, webcam, dock, and Bluetooth headset can present different inputs. Choose the intended microphone rather than assuming a new accessory became the default.
If available, use Make a test call and listen to playback. Microsoft notes that this feature is unavailable in Teams on the web. Follow the current Teams microphone guide for your version.
3. Check whether Windows hears you
In Windows 11, open Settings, System, Sound. Under Input, select the microphone and use its test controls. Speak normally and review the result.
If Windows does not detect your voice, the problem extends beyond one meeting. Check the connection and input volume before reinstalling software. Microsoft's Windows microphone troubleshooting guide explains the tests and access controls.
4. Review microphone permissions
Windows 11 permissions are under Settings, Privacy & security, Microphone. Check microphone access and the applicable app or desktop-app permission. If business policy locks a control, ask your administrator to review it.
In Teams for the web, review microphone permission for the Teams site and confirm the browser's selected input. Operating-system access does not necessarily resolve a blocked site permission. For a Mac or phone, follow the platform-specific section in Microsoft's Teams guide.
5. Compare a known-good setup
Try another supported microphone or a direct connection instead of the dock. If practical, compare the desktop app with Teams in a supported browser. Change only one variable per test.
This narrows the investigation; it does not prove an accessory is defective. Record which combination works. Arrange app or computer restarts outside an active meeting.
