When people can’t hear you through your headset, the microphone usually works fine. Windows or your meeting app is listening to a different input, or the mic is blocked by a mute switch or a privacy setting.
Start with Windows’ own microphone test. Go to Settings > System > Sound, choose your headset under Input, select the arrow next to it, and choose Start test. If the level moves when you talk, the headset is working and the problem is in Teams, Zoom or the browser, or in the Windows privacy switches that let those apps use the mic. If nothing moves, it’s the connection, a mute or privacy setting, or the driver.
USB, 3.5mm combo-jack and Bluetooth headsets each fail in their own ways, so each has its own section below.
Try these first
- Check the headset’s mute button or inline cable switch; many headsets also mute when you raise the boom.
- Settings > System > Sound: under Input, choose the headset rather than the laptop’s built-in mic.
- Settings > Privacy & security > Microphone: turn on Microphone access, Let apps access your microphone, Microsoft Teams (work or school) and Let desktop apps access your microphone.
- In Teams or Zoom, pick the headset by name in device settings instead of a default device.
- Unplug and reconnect the headset, then fully quit and reopen the meeting app.
- On Windows 11, Windows key + Alt + K toggles mic mute in apps that support it, such as Teams; check the app’s mute icon afterward.
Find where your voice is getting lost
| What you see | Likely cause | What to do |
|---|---|---|
| Windows mic test moves, but Teams or Zoom hears nothing | The app is using a different input, or a Windows privacy switch blocks the app | Select the headset in the app’s settings; check microphone privacy switches |
| Headset listed, but the mic test stays flat | Muted, input volume at zero, or a privacy setting | Mute switch, input volume, privacy settings |
| Headset not listed as an input at all | Connection, jack type, Bluetooth mode or driver | Section for your headset type |
| Mic works in one app and not another | One app has exclusive control, or app permission is off | Exclusive-mode setting; app permissions |
| People say you sound faint | Input volume or Microphone Boost low, or boom too far away | Levels and mic position |
| Bluetooth audio turns flat and tinny when a call starts | Headset switched to hands-free mode to use its mic | Expected; use a USB dongle or wired headset for better quality |
| Headset mic works on your phone, never on this PC | Desktop with separate pink and green jacks, the jack set to headphones, or a headphone-only jack such as a monitor’s | 3.5mm section: Y adapter, the headset option when asked what you plugged in, or plug into the computer |
| You can’t hear anything either, or the speaker icon shows a red X | An audio output or driver problem, not the mic | Fix sound first with our no audio output device guide; the mic usually returns with it |
| Worked until a Windows update | Audio driver changed | Roll back the driver |
Fixes by headset type
USB headsets and USB dongles
A USB headset is a sound device of its own, with its own name in the input list. Select it by name; if Windows switched back to the laptop’s built-in mic, that’s the most common reason colleagues hear keyboard noise but not you. Plug it directly into the computer rather than a hub, and try another port if it doesn’t appear. If Windows doesn’t detect it at all, see USB device not recognized.
Many business headsets have a companion app from the headset maker that handles firmware updates and call-button behavior. If the headset’s mute light and Teams show different mute states, updating the headset firmware through that app is the first thing to try.
3.5mm headsets: combo jack or separate jacks
Most laptops have a single combo jack for headphones and a microphone together. It needs a headset plug with four contacts, which you can recognize by three thin insulating bands dividing the metal plug into four sections. A plug with two bands has only three contacts and no mic contact, and ASUS notes that a three-conductor mic won’t work in a combo jack.
- Headset with two plugs (pink and green) on a laptop with one jack: use a splitter adapter that combines them into one four-contact plug.
- Four-contact headset on a desktop with separate jacks: use a Y adapter that splits it into mic and headphone plugs. The pink jack is the mic input and green is the headphone output.
- Plugged into a monitor: a monitor’s audio jack is usually headphone-only, so plug the headset into the computer itself.
- Desktop front-panel jacks: if nothing works there, try the rear jacks on the motherboard; front panels aren’t always connected internally.
Some laptops’ audio software shows a pop-up asking what you plugged in. Choose the headset option, not headphones, or the mic won’t be enabled.
Bluetooth headsets
On Windows 11, a Bluetooth headset with a mic shows up as one output and one input. Windows switches it into hands-free mode on its own when an app opens the mic, so just pick the headset under Input. On Windows 10, it usually appears as two devices, one ending in Stereo and one ending in Hands-Free. The microphone only exists on the Hands-Free entry, so pick that one as your input.
If Windows 11 still shows two entries, update the audio driver from the PC maker’s support page and pair the headset again. Sound turning flat as soon as the mic opens is expected, not a fault; our Bluetooth troubleshooting guide explains the hands-free versus stereo trade-off and covers headsets that won’t pair or keep dropping.
If there’s no headset input at all, Windows isn’t loading the headset’s call profile. Remove the headset in Settings > Bluetooth & devices > Devices and pair it again. If the mic still doesn’t appear, open Control Panel > Devices and Printers, right-click the headset, choose Properties, and on the Services tab make sure Handsfree Telephony is checked. People sometimes clear it to keep music in stereo, and that removes the mic. If it’s already checked, clear it, select Apply, check it again and restart.
If the headset is also connected to your phone, the phone can grab the mic. Disconnect it from the phone and try again.
Windows settings: input device, volume and privacy
Choose and test the input
In Settings > System > Sound, under Input, pick your headset in Choose a device for speaking or recording. Select the arrow next to it to reach Input volume and Microphone test. Set input volume high enough that the test level moves clearly when you speak normally.
On Windows 10, choose the headset under Choose your input device, open Device Properties, then select Additional device properties. On the Levels tab, raise Microphone and, if your audio driver offers it, Microphone Boost. On Windows 11, the same Levels tab is under More sound settings > Recording > the headset’s Properties.
Privacy switches
Go to Settings > Privacy & security > Microphone and turn on Microphone access and Let apps access your microphone. In the app list below them, the current Teams app has its own entry, Microsoft Teams (work or school), which must be on too. Desktop programs such as Zoom and web browsers can’t be switched on one by one; they all share Let desktop apps access your microphone, so that last switch is easy to miss. After changing anything, close your apps and restart.
On Windows 10, it’s Settings > Privacy > Microphone, where the switches are Microphone access for this device (under Change), Allow apps to access your microphone and Allow desktop apps to access your microphone.
A disabled or hidden input
Select More sound settings and open the Recording tab. Right-click the empty space, choose Show Disabled Devices, and enable your headset if it appears greyed out. Speak and watch its level bar; if it moves here, Windows is hearing you.
Built-in troubleshooter
In Settings > System > Sound, scroll to Advanced and choose Input devices under Troubleshoot common sound problems.
On Windows 10, go to Settings > Update & Security > Troubleshoot > Additional troubleshooters and run Recording Audio.
Teams, Zoom and browser settings
Meeting apps keep their own device choice, separate from Windows.
- Teams desktop app: before a meeting, select Settings and more (the three dots) > Settings > Devices, choose the headset as the microphone, and use Make a test call to hear yourself back. During a meeting, select the arrow next to Mic, choose More audio settings and pick the headset without leaving the call.
- Zoom: if the microphone button in the meeting toolbar says Join Audio, Zoom isn’t using any microphone yet; select it and choose Join with Computer Audio. To change devices, open Settings > Audio, choose the headset under Microphone and use Test Mic.
- Meetings in a browser: Chrome and Edge count as desktop apps, so they rely on the desktop apps switch above. The meeting site also needs its own microphone permission, set from the site controls beside the web address.
Works in one app, silent in another
Some apps take exclusive control of the mic and lock others out. In More sound settings > Recording, open the headset’s Properties, go to Advanced, and clear Allow applications to take exclusive control of this device. While you’re in the headset’s properties, turn off any audio enhancements if the option is there; Dell suggests this when a microphone sounds distorted.
Also quit any other calling app running in the system tray. Two meeting apps fighting over one headset is a classic cause of “it worked in my last meeting.”
Rather have a technician sort it out?
If people still can’t hear you, a technician can connect remotely with your approval, check your headset’s settings in Windows and Teams, and test it with you on a call. A GoProIT technician can connect remotely, with your permission, and fix it while you watch. $59 per fix, Mon–Fri 8am–8pm ET.
Drivers and updates
- Right-click Start, open Device Manager, and expand Audio inputs and outputs and Sound, video and game controllers.
- If the mic stopped right after an update, start here: open the device’s Properties > Driver tab and choose Roll Back Driver if it’s available.
- For a USB or Bluetooth headset, right-click the headset entry, choose Uninstall device and leave the driver box unchecked. These headsets normally use drivers built into Windows, so reconnecting the headset reinstalls them.
- For the laptop’s own jack or built-in mic, reinstall the audio driver from the laptop maker’s support page for your model, not a generic one. The no-audio guide linked above gives the full order, including the Intel Smart Sound Technology driver many recent Intel laptops need first.
- If a device doesn’t come back, right-click Sound, video and game controllers and choose Scan for hardware changes.
On many ASUS laptops, the internal microphone is integrated with the camera and uses the camera driver, while external mics use the audio driver. If the built-in mic disappeared along with the webcam, our laptop camera guide is the better starting point.
For offices: one person or everyone?
A note saying some settings are managed by your organization, with the microphone switches greyed out, means a policy is in charge. The Group Policy setting Let Windows apps access the microphone (Computer Configuration > Administrative Templates > Windows Components > App Privacy) can force microphone access off, and Intune delivers the same setting as Privacy/LetAppsAccessMicrophone. Microsoft documents it as controlling Windows apps, the ones listed individually on the Microphone privacy page (the current Teams app is one), rather than desktop programs such as Zoom or Chrome. Check it before troubleshooting a whole team’s headsets.
When many people report mic problems in Teams at once, compare what they share: the same headset model, the same laptop model after a driver update, or the same Teams version. Standardizing on one or two USB headset models with dongles removes most Bluetooth and combo-jack variables. Our Microsoft 365 management service handles day-to-day Microsoft 365 administration for the office, from adding and removing users to security settings.
If a headset works on the laptop but is silent inside a Remote Desktop session, the session isn’t passing the mic through. In Remote Desktop Connection, select Show Options > Local Resources > Remote audio > Settings, choose Record from this computer and reconnect. On a server you manage, also check that the Group Policy setting Allow audio recording redirection (Windows Components > Remote Desktop Services > Remote Desktop Session Host > Device and Resource Redirection) isn’t disabled.
If you’d rather not work through the steps above, this is a typical $59 remote fix. In one remote support session (it needs your approval, and you can end it at any time), a technician can join a test call with you, hear the result and change settings in Windows and Teams.
When the headset or jack is faulty
- The mic fails on two different computers or on a phone: the headset is faulty. Replace it or use the warranty.
- It only works when the cable is bent or held a certain way: a broken wire inside the cable, usually near the plug or the earcup.
- Every headset fails in this jack, but the same headsets work elsewhere: the jack or the audio circuit on the laptop is damaged. A USB headset is a practical workaround until it’s repaired.
- The boom mic crackles or cuts out when moved: a worn boom hinge. That’s common on older headsets and isn’t fixable in software.
Common questions
Why does my headset audio work but not the microphone?
When a headset mic is not working on a laptop, usually Windows or the meeting app is still using the laptop’s built-in mic, or the headset is muted by a button or a raised boom. With 3.5mm headsets, the plug may not match the jack: a combo jack needs a four-contact plug. If a Bluetooth headset mic is not working on Windows 10, pick the Hands-Free entry as your input, because the mic only works in that mode; Windows 11 shows the headset as one input and switches modes for you.
Why is the mic button greyed out in my Teams meeting?
The meeting organizer or a presenter has probably turned off Allow mic for attendees in the meeting options, so attendees can’t unmute. Nothing is wrong with your headset or Windows. Raise your hand or message the organizer and ask them to allow your mic. If the button works but Teams says it can’t find a microphone, that’s a device problem: check Settings and more, Settings, Devices.
How do I make my headset the default microphone in Windows 11?
Go to Settings, System, Sound and choose your headset under Input in Choose a device for speaking or recording. Windows also keeps a separate default for calls: select the headset, and if Set as default sound device is offered, choose Use as default for communications. Teams and Zoom keep their own microphone choice too, so select the headset there and confirm with the app’s mic test or test call.
Why does my microphone work in Zoom but not in Teams?
Your headset is fine, so look at Teams. The current Teams app has its own switch in Windows: go to Settings, Privacy & security, Microphone and turn on Microsoft Teams (work or school). Zoom uses the separate desktop apps switch, which is why one can work while the other can’t. Then quit Zoom fully, open Teams’ Settings and more, Settings, Devices, choose the headset by name and make a test call.
Do I need a splitter for my headset?
Only if the plugs and jacks don’t match. A headset with separate pink and green plugs needs a splitter to work in a laptop’s single combo jack. A headset with one four-contact plug needs a Y adapter for a desktop with separate mic and headphone jacks. USB and Bluetooth headsets never need one.
Why is my microphone so quiet?
Check the input volume in Settings, System, Sound for your headset, and the Levels tab in the headset’s recording properties (More sound settings > Recording > Properties), where Microphone Boost appears if the audio driver offers it. Position the boom about two finger-widths from the corner of your mouth. Also turn off automatic volume adjustment in your meeting app if it keeps lowering your level.
