When your microphone is silent in Teams or Zoom on Windows 11, work through four layers in order: the mute controls, the Windows privacy toggles, the input device Windows has selected, and the device chosen inside the app. Most cases are fixed by turning on Let desktop apps access your microphone or by picking the right microphone in the app's own audio settings.
Who this is for and what you will have at the end
This guide is for Windows 11 users whose microphone is not picked up in Microsoft Teams or Zoom, whether it is a laptop mic, a USB headset or a Bluetooth headset. At the end you will know whether the fault is the hardware, Windows or the app, and you will have a working input confirmed by a test recording.
You do not need administrator rights for most steps. Uninstalling an audio driver in Device Manager may need them on a work PC, and on a managed device an IT policy can lock some settings.
Step 1: Rule out mute and hardware
Do these first, because they take under a minute.
- In the meeting controls, look at the Mic icon. In Teams, if it has a line through it, select Unmute mic. In Zoom, click the muted audio icon to unmute. In Zoom, if you still cannot unmute, the host may have muted you; send them a chat message.
- Check for a physical mute button or switch on the headset or external microphone. Microsoft's page lists this as a common cause for "others can't hear me".
- If the headset has a boom microphone, make sure it is positioned near your mouth.
- Make sure the cable is fully inserted. If Zoom does not detect the microphone, unplug it and plug it back in.
- For a wireless headset, confirm it is on, charged and connected. Teams guidance adds that a Bluetooth microphone should not be connected to another device at the same time. If Bluetooth is the issue, see our guide to Bluetooth not working on Windows 11.
If you recently updated Teams or Windows, install any pending updates and restart. Microsoft's Teams troubleshooting begins with updating Teams and the operating system.
Step 2: Check the Windows microphone privacy settings
Windows can block microphone access for all apps or for desktop apps specifically. This is the most common cause when the microphone works in one place but not in another.
- Open Start > Settings > Privacy & security > Microphone.
- Turn on Microphone access.
- Turn on Let apps access your microphone.
- Scroll down and turn on Let desktop apps access your microphone.
Microsoft notes that desktop apps do not appear in the list of apps on this page, and that the desktop toggle is the way to allow them. You cannot turn off microphone access for individual desktop apps, so there is no separate switch for Zoom or classic desktop clients.
For Teams, the Microsoft article also lists Microsoft Teams (work or school) in this list. Make sure it is on. If every toggle is already on, turn them off and on again, close all apps and restart the PC, which is Microsoft's own suggestion.
If your microphone is built into a webcam, also check Start > Settings > Privacy & security > Camera and confirm Camera access is on, as Microsoft's page directs.
Step 3: Check the input device in Windows
Even with permission granted, Windows may be sending audio from the wrong device, such as a monitor with a microphone or a disconnected headset.
- Open Start > Settings > System > Sound.
- Under Input, choose your microphone in Choose a device for speaking or recording.
- Select the arrow next to the device to open its properties.
- Under Microphone test (or Input settings, depending on the build), select Start test, speak normally, select Stop test, then under Recorded sample select Play.
- If playback is silent or very quiet, raise the Input volume slider and test again.
This test is the dividing line. If the recording works here, the hardware and Windows are fine and the problem is in the app. If it does not work, continue with the Windows fixes below before changing anything in Teams or Zoom.
If the microphone does not appear in the list, select Add device to pair a Bluetooth microphone, as the Teams article suggests.
Enable the device in the classic Sound panel
If problems persist, go to Advanced > More sound settings on the Sound page. On the Recording tab, right-click your microphone and select Enable if it is disabled. This step comes from Microsoft's Teams guidance.
Run the Windows audio troubleshooter
On Settings > System > Sound, scroll to Advanced and select Input devices under Troubleshoot common sound problems. Select All sound devices under Advanced for more options. Follow the prompts and test again.
Step 4: Choose the microphone inside Teams or Zoom
Each app keeps its own device selection, so a correct Windows input does not guarantee the app is using it.
Microsoft Teams
Before a meeting:
- Select Settings and more (the three dots) > Settings > Devices.
- Under Audio settings, choose your microphone from the Microphone drop-down.
- Optionally select Make a test call to try it. Microsoft notes the test call is English-only and not available in Teams on the web.
During a meeting, select the drop-down arrow next to Mic, then More audio settings, and choose the right microphone. If the microphone is not in the list, unplug it and plug it back in.
Zoom
- Sign in to the Zoom desktop app, click your profile picture, then click Settings.
- Open the Audio tab.
- Under Microphone, test the microphone, select the one you want from the drop-down and adjust the Input Volume slider.
- Optionally, open the advanced audio settings and turn off Signal processing by Windows audio device drivers. Zoom lists this as something to try; change it only if you have audio problems, and note what it was before so you can restore it.
To switch microphones mid-meeting, click the up arrow next to Mute on the toolbar and pick another device. Zoom's guidance for Bluetooth headphones is to select the headphones for both microphone and speaker, then join a test meeting to confirm.
Teams or Zoom in a web browser
If you use Teams or Zoom in a web browser, the browser needs permission too. Microsoft's article gives these paths:
| Browser | Path |
|---|---|
| Edge | Settings and more > Settings > Cookies and site permissions > Microphone, then turn on Ask before accessing (recommended) |
| Chrome | Settings > Privacy and security > Site settings > Permissions > Microphone, confirm the device, and under Default behavior select Sites can ask to use your microphone |
Some settings may be locked by your IT administrator.
Step 5: Fix driver and detection problems
If Windows does not see the microphone at all, or it vanishes after an update, reset its driver. This procedure is from Microsoft's "Fix microphone problems" page.
- Right-click Start and select Device Manager.
- Expand Sound, video and game controllers.
- Right-click each audio device, select Uninstall device, tick Attempt to remove the driver for this device, and select Uninstall. Repeat for the other audio devices.
- Restart the PC. Windows should reinstall the devices automatically.
- If it does not, open Device Manager, right-click Sound, video and game controllers and select Scan for hardware changes.
- To update rather than reinstall, right-click your audio driver and select Update driver.
Be careful on a work laptop: the audio driver may be supplied by the manufacturer or by your IT team, and removing it could leave you without sound until it is reinstalled. If you are unsure, ask your IT team first.
Step 6: Remote Desktop and virtual machines
If you join meetings from a remote Windows session, the microphone on your local PC has to be passed through. In Remote Desktop Connection, go to the Local Resources tab, select Settings under Remote audio, set Remote audio playback to Play on this computer and Remote audio recording to Record from this computer, then select OK. Microsoft also notes that Teams in a virtual desktop may need an optimized setup; that is an administrator topic.
Last resort: use your phone for audio
If a Teams meeting shows a Call me back option, you can select it, enter your phone number and select Call me. Audio then comes from your phone while you keep sharing content from the PC. This is a stopgap to get through the meeting, not a fix.
Quick diagnosis table
| Symptom | Most likely cause | Fix |
|---|---|---|
| Works in Windows test, silent in app | Wrong device selected in app | Step 4 |
| Silent in Windows test | Privacy, driver or hardware | Steps 2, 3 and 5 |
| Fine until a Windows update | Privacy toggles reset or driver changed | Steps 2 and 5 |
| Bluetooth headset connected, no one hears you | Headset set as speaker only, or connected elsewhere | Steps 1 and 4 |
| Desktop apps blocked but browser works | Desktop apps toggle is off | Step 2 |
Verify the fix
- Run the Windows input test and confirm the recorded sample plays back clearly.
- In Teams, use Make a test call. In Zoom, use the Audio tab test or join a test meeting.
- Ask a colleague to join a short call and confirm they hear you at a normal volume.
If you work from home often, it also helps to have a reliable network. Our guide on fixing Wi-Fi problems on Windows 11 covers the common causes of choppy calls.
Checklist
- Unmute in the app and check the physical mute switch.
- Settings > Privacy & security > Microphone: Microphone access, Let apps access your microphone and Let desktop apps access your microphone all on.
- Settings > System > Sound: correct input selected, Start test works.
- Pick the microphone explicitly in the Teams or Zoom audio settings.
- Reinstall the audio device in Device Manager if it is missing or detection is flaky.
- On Remote Desktop, record from the local computer.
