When nobody can hear you on a call, the cause is almost always one of a handful of settings, and they’re quick to check in the right order. Start by finding out where the sound stops.
Test it first: open the free Microphone Test in your browser.
- If the level moves there but not in Zoom or Teams, your mic works and the problem is that app’s settings.
- If nothing moves anywhere, work through the steps below.
1. Mute switches and connection
- Check the mute button or slider on the headset or its cable; many glow red when muted.
- Re-plug USB headsets, ideally directly into the computer. For 3.5 mm jacks, make sure the plug goes in the microphone port (or a combined headset port).
- Bluetooth headsets: re-pair them, and note that some switch to lower-quality audio when the microphone is in use.
2. Windows privacy settings
Go to Start → Settings → Privacy & security → Microphone and turn on:
- Microphone access
- Let apps access your microphone
- Let desktop apps access your microphone: browsers and most meeting apps are desktop apps.
3. Choose the right input device
Go to Settings → System → Sound → Input → Choose a device for speaking or recording. Laptops with a webcam and a headset can have three or more microphones; select the one you’re actually using.
On the same page, Windows has a Start test button for a quick check.
4. Check the input volume
Select your microphone, open Input settings and raise Input volume. If the level is fine on our test but people say you sound quiet, raise it in small steps.
5. Check the app and browser
- Meeting apps (Teams, Zoom, Discord) each have their own Microphone setting in their audio options. Make sure it matches the device you chose in Windows.
- Browsers: click the icon to the left of the address bar, set Microphone to Allow, then reload the page.
6. Close apps that may be holding the microphone
Some apps keep exclusive use of a microphone. Close other meeting or recording apps, or restart the computer, then test again.
7. Run the sound troubleshooter
Go to Settings → System → Sound, scroll to Advanced and choose Troubleshoot common sound problems.
8. Reinstall the audio driver
Right-click Start → Device Manager, expand Sound, video and game controllers, right-click your audio device and choose Update driver.
If that doesn’t help, choose Uninstall device, restart, then use Action → Scan for hardware changes.
Still nothing?
Try the microphone on another computer or phone. If it fails there too, the microphone or its cable is faulty. Check the warranty before replacing it.
