The 12 Fixes in Detail

Each fix shows when to use it, why it works, the exact steps and commands, what success looks like and what to do if it fails.

Progress: 0/12
01Check the basics: plug, mute switch, right jack, another deviceData risk: None⏱ 5 minAlways start here
Use this whenWindows shows no external microphone, the level bar never moves or the mic suddenly went silent.
Why it worksA loose plug, a hardware mute switch, the wrong jack or a faulty cable causes a large share of cases. A two-minute check can save an hour of settings changes.
  1. Replug the microphone firmly, wait for the Windows connection sound and restart the PC once.
  2. Look for a mute control. Many headsets and USB mics have a mute switch, button or knob. Many laptops have a mic mute key (often F4 or F8 with a mic icon). In supported apps such as Teams you can also use Windows + Alt + K to mute and unmute.
  3. Use the right jack. A laptop with one 3.5 mm combo jack needs a headset plug with a mic (usually three black bands, four metal sections). A mic-only plug or a stereo-only plug needs a splitter or a USB audio adapter. On a desktop, use the pink mic jack, not the green or blue one.
  4. Try another USB port and plug straight into the PC, not into a hub or dock. Try a different cable if the mic has a removable one.
  5. Test on another device, such as a phone or another PC. If it fails there too, the microphone, cable or adapter is faulty (Fix 12).
  6. Unplug other headsets, webcams and audio gadgets for now so they cannot take over the input.
💡
Quick plug check

A plug with two black bands is usually stereo-only or mic-only. A plug with three black bands usually carries both headphone sound and the microphone.

🎯What success looks like: The microphone is firmly connected, not muted, plugged into the right port and works on another device.
↪️If it fails: If it also fails on another device, skip to the hardware test in Fix 12. If it works elsewhere, continue with Fix 2.
02Choose the right input device and raise the volumeData risk: None⏱ 5 minMic listed but silent
Use this whenThe microphone is listed but nothing is recorded, the level bar does not move, or the sound is very quiet.
Why it worksWindows records from one default input at a time. If it points at the laptop's built-in mic or the volume is near zero, your external microphone seems dead even though it works.
  1. Open Settings → System → Sound and scroll to Input.
  2. Under Choose a device for speaking or recording, select your external microphone by name (for example Headset Microphone, USB Audio Device or the brand name).
  3. Click that device and check Input volume. Move the slider to a high value (70 to 100) and make sure the mute option is off.
  4. Click Start test and speak. The bar should move. Stop the test when you are done.
  5. If the bar moves but your voice is still too quiet, go to Fix 7 for the Levels and boost settings.
✅
Wording varies by build

Windows 11 updates move some labels around. If you do not see an option, look for the same words inside the selected microphone's Properties page.

🎯What success looks like: Your external microphone is the selected input, and the test bar moves when you speak.
↪️If it fails: If it is not listed, go to Fix 4 (disabled device) and Fix 9 (driver). If the test works but apps do not, go to Fix 3 and Fix 6.
03Allow microphone access in Privacy settingsData risk: None⏱ 5 minWorks in test, not in apps
Use this whenThe microphone works in the Sound settings test but Teams, Zoom, Discord, Chrome or another app hears nothing, or an app says it cannot access the microphone.
Why it worksWindows blocks apps from the microphone unless access is allowed. This often turns off after an update, a privacy clean-up or a managed-device policy.
  1. Open Settings → Privacy & security → Microphone.
  2. Turn on Microphone access.
  3. Turn on Let apps access your microphone, then scroll the app list and make sure the app you use is switched On.
  4. Turn on Let desktop apps access your microphone. Teams, Zoom, Discord and most classic programs count as desktop apps and use this switch.
  5. Check the Recent activity list on the same page. It shows which apps used the microphone lately, which helps confirm that access works.
  6. Restart the app, or sign out and in again, and test it.
⚠️
Work or school PC, or security software

If the switches are greyed out, an organisation policy controls them. Ask your IT team. Some security suites also have a microphone protection feature that can block apps, so check their settings.

🎯What success looks like: The three microphone access switches are On, and your app can hear the microphone.
↪️If it fails: If everything is on and the app is still silent, set the right microphone inside the app (Fix 6).
04Enable a disabled microphone and set it as defaultData risk: None⏱ 10 minMic not showing up
Use this whenThe external microphone is missing from the Sound settings list, or it appears but Windows never uses it.
Why it worksWindows can disable an input device after an update or a driver change. The classic Sound panel shows disabled and disconnected devices so you can enable them and set them as the default.
  1. Press Windows + R, type mmsys.cpl and press Enter. Open the Recording tab.
  2. Right-click an empty area and tick Show Disabled Devices and Show Disconnected Devices.
  3. Right-click your microphone. If you see Enable, click it.
  4. Right-click it again and choose Set as Default Device, then Set as Default Communication Device.
  5. Speak. The green bar next to the mic should move.
  6. You can also check Settings → System → Sound → Advanced → All sound devices (name varies by build) for a microphone marked as not allowed, and choose Allow.
Run dialog (Windows + R)
mmsys.cpl
  • mmsys.cpl — opens the classic Sound control panel with the Recording tab
🎯What success looks like: The microphone shows as enabled with a green tick, and its bar moves when you speak.
↪️If it fails: If the microphone is not listed even with hidden devices shown, check the driver and the connection in Fix 9 and Fix 10.
05Run the Recording Audio troubleshooterData risk: None⏱ 5 minLet Windows check it
Use this whenYou are not sure what is wrong, or the basic checks did not help.
Why it worksThe built-in troubleshooter checks the audio services, the default device, the volume and common driver problems, and it can fix some of them automatically.
  1. Open Settings → System → Troubleshoot → Other troubleshooters.
  2. Find Recording Audio and click Run. Windows may open the Get Help app to run it.
  3. Choose your external microphone when asked and follow the suggestions it shows.
  4. Apply any fix it offers, restart the PC and test the microphone again.
🎯What success looks like: The troubleshooter reports a fix or reports that no problem was found, and your microphone works.
↪️If it fails: If it finds nothing but the mic still fails, move on to the app settings (Fix 6) and the audio services (Fix 8).
06Set the microphone inside Teams, Zoom, Discord or your browserData risk: None⏱ 10 minOne app does not hear you
Use this whenWindows tests fine but one app (Teams, Zoom, Discord, Chrome, Edge, OBS, a game) cannot hear you.
Why it worksMost apps keep their own microphone choice. If they still point to the old or built-in microphone, they ignore your new external one.
  1. Teams: click the three dots, open Settings → Devices and choose your microphone.
  2. Zoom: open Settings → Audio → Microphone and choose your microphone. Click Test Mic.
  3. Discord: open User Settings → Voice & Video, set Input Device to your microphone and run Let's Check.
  4. Chrome or Edge: click the lock icon in the address bar, set Microphone to Allow, then open the site's settings and choose the right input. You can also review all sites under the browser's Privacy settings, in the Site permissions or Microphone section.
  5. Close other apps that might hold the microphone, such as recorders or other meeting apps, then restart the app you want to use.
  6. Remote Desktop: before connecting, open Show options → Local Resources → Remote audio → Settings and set Remote audio recording to Record from this computer.
  7. Virtual machine: make sure the VM has audio input enabled and the USB microphone is passed through to the VM.
💡
Use the app's own mic test first

Most meeting apps have a test button. If the app's own test shows your voice, the microphone works and any remaining problem is in the meeting settings.

🎯What success looks like: The app's microphone test shows a moving level bar and other people can hear you.
↪️If it fails: If the app still cannot hear you, check Windows exclusive mode and enhancements in Fix 7.
07Turn off exclusive mode and enhancements, and fix levelsData risk: None⏱ 10 minQuiet, distorted or app conflicts
Use this whenThe sound is very quiet, muffled, distorted or noisy, or one app works and another then goes silent.
Why it worksWindows lets one app take exclusive control of the microphone, which can block the others. Audio enhancements and a wrong format can also muffle or cut the sound.
  1. Press Windows + R, run mmsys.cpl and open the Recording tab. Double-click your microphone.
  2. On the Advanced tab, untick Allow applications to take exclusive control of this device.
  3. Still on Advanced, set Default Format to 1 channel, 16 bit, 48000 Hz (or 44100 Hz) and click Apply. Try the other formats if one does not work.
  4. On the Levels tab, make sure the microphone is not muted and set the volume high. If your voice is still too quiet, raise Microphone Boost a little. If there is hiss, lower it.
  5. Turn enhancements off. Open Settings → System → Sound, click your microphone and set Audio enhancements to Off (or the device default). Also turn off noise suppression or voice effects in any sound software from the maker, such as the Realtek Audio Console, Nahimic or Dolby.
  6. Click OK and test again.
🎯What success looks like: Your voice is clear at a normal volume, and several apps can use the microphone without blocking each other.
↪️If it fails: If the sound is still wrong, update or reinstall the audio driver in Fix 9.
08Restart the Windows Audio servicesData risk: None⏱ 5 minAudio stuck after sleep or update
Use this whenThe microphone vanished after sleep, a Windows update or unplugging a device, and a restart is not convenient.
Why it worksTwo services control sound: Windows Audio and Windows Audio Endpoint Builder. If they hang, devices disappear or stop recording. Restarting them reloads the audio system.
  1. Press Windows + R, type services.msc and press Enter.
  2. Find Windows Audio, right-click it and choose Restart. Do the same for Windows Audio Endpoint Builder. Confirm if Windows asks about dependent services.
  3. Double-click each one and make sure Startup type is Automatic.
  4. Or open Command Prompt (Admin) and run the commands below instead. Then test the microphone.
Command Prompt (Admin)
net stop audiosrv
net stop AudioEndpointBuilder
net start AudioEndpointBuilder
net start audiosrv
sc config audiosrv start= auto
sc config AudioEndpointBuilder start= auto
  • net stop / net start — stops and starts the Windows Audio and Endpoint Builder services in the right order
  • sc config … start= auto — makes both services start automatically with Windows
🎯What success looks like: Both services show Running, and the microphone is listed again and records.
↪️If it fails: If the services will not start, repair system files in Fix 11 and check the driver in Fix 9.
09Update, reinstall or roll back the audio driverData risk: Low⏱ 15–30 minStarted after an update
Use this whenThe microphone is missing from Device Manager, shows a yellow warning, or stopped working after an update or driver install.
Why it worksThe audio driver connects the microphone to Windows. A damaged, outdated or mismatched driver can hide the device. Reinstalling it, updating it or going back to a working one often restores it.
  1. Right-click Start and open Device Manager. Expand Audio inputs and outputs and Sound, video and game controllers. Look for your microphone and your sound chip (for example Realtek).
  2. Right-click the microphone and choose Update driver → Search automatically for drivers. Also check Settings → Windows Update → Advanced options → Optional updates for audio drivers.
  3. For the best match, download the newest audio driver from your laptop or motherboard maker's support page (not a random driver site) and install it.
  4. If it still fails, right-click the device and choose Uninstall device (do not tick the option to delete the driver software), then restart. Windows reinstalls it.
  5. If it began after an update, double-click the device, open the Driver tab and click Roll Back Driver if the button is available.
  6. As a test, choose Update driver → Browse my computer → Let me pick from a list and pick High Definition Audio Device, the generic Microsoft driver. If the microphone works with it, you can keep it.
⚠️
Use official drivers

Driver updater tools from unknown sites often install the wrong driver or unwanted software. Use Windows Update or your PC maker's support page.

🎯What success looks like: The microphone shows under Audio inputs and outputs with no warning icon, and it records.
↪️If it fails: If it still fails, check the connection type in Fix 10, and look at removing a recent update in Fix 11.
10Fix jack, USB and Bluetooth problemsData risk: None⏱ 15–20 minDepends on how it connects
Use this whenA 3.5 mm headset is not detected, a USB microphone keeps disconnecting, or a Bluetooth headset plays sound but the microphone does nothing.
Why it worksEach connection type fails in its own way: the wrong audio profile on Bluetooth, power saving on USB, or the jack type and jack prompt on 3.5 mm ports.

3.5 mm jack

  1. When you plug in, answer the What device did you plug in? prompt (if shown by the Realtek Audio Console) with Microphone or Headset.
  2. On a desktop, use the rear panel jack. Front-panel jacks need the case cable connected to the motherboard, and the BIOS option for HD Audio enabled.

USB microphone or audio interface

  1. Plug it straight into a different USB port. Avoid hubs and docks, and try a USB 2.0 port if you have one.
  2. Open Control Panel → Power Options → Change plan settings → Change advanced power settings → USB settings → USB selective suspend setting and set it to Disabled.
  3. Check the microphone's own gain knob, mute light and any software from the maker. For an XLR microphone on an audio interface, check the gain knob and 48V phantom power for condenser microphones.

Bluetooth headset

  1. Open Settings → Bluetooth & devices → Devices, remove the headset and pair it again. Disconnect it from your phone first if it connects to both.
  2. In Settings → System → Sound, choose the Headset (Hands-Free) entry for input. Bluetooth headset microphones use that profile, and the sound quality drops while the mic is active. That is normal.
💡
Why Bluetooth sound gets worse

When the microphone starts, many Bluetooth headsets switch to a lower-quality Hands-Free mode so they can send your voice. Quality returns when the call ends.

🎯What success looks like: The microphone connects reliably and the correct device shows as the input.
↪️If it fails: If your connection type still fails, test with a different connection type, for example a USB headset, to find out whether the PC or the microphone is at fault (Fix 12).
11Remove a recent update and repair Windows filesData risk: Low⏱ 20–40 minBroke right after an update
Use this whenThe microphone stopped right after a Windows update, or audio services and settings keep failing.
Why it worksAn update can replace an audio component and break a working setup. Uninstalling it, or restoring system files, brings back the working version without touching your documents.
  1. Open Settings → Windows Update → Update history → Uninstall updates. Pick the most recent update from around the time the microphone broke and click Uninstall.
  2. Or use System Restore: press Windows + R, run rstrui, and choose a restore point from before the problem.
  3. Open Command Prompt (Admin) and run the two repair commands below, then restart.
  4. If you removed an update, pause updates for a few days (Settings → Windows Update → Pause updates) until a fixed update or driver is available.
Command Prompt (Admin)
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
  • DISM … /RestoreHealth — repairs the Windows component store
  • sfc /scannow — checks protected system files and replaces damaged ones
🎯What success looks like: SFC and DISM finish without unrepaired errors, and the microphone works again after the restart.
↪️If it fails: If it still fails, reset the sound settings and test the hardware in Fix 12.
12Reset sound settings, test the hardware and repair Windows (last resort)Data risk: Low⏱ 30–90 minNothing else worked
Use this whenEverything above failed, or the microphone also fails on other devices.
Why it worksResetting sound settings clears every custom device and app volume choice. A hardware test then shows whether the cause is Windows or the microphone, cable, adapter or the PC's audio jack.
  1. Open Settings → System → Sound → Advanced and choose Reset sound devices and volumes for all apps to the recommended defaults. Then select your microphone again (Fix 2).
  2. Test the hardware. Try the microphone on another PC or a phone. Try a different cable or adapter. Plug in a USB headset or a known-good microphone to the same PC to see whether the PC's audio works at all.
  3. Repair install Windows 11. Open Settings → System → Recovery and look for Fix problems using Windows Update, or run setup.exe from a Windows 11 ISO and choose Keep personal files and apps.
  4. If a repair install does not help and another microphone works, replace the faulty microphone, cable or adapter. If no microphone works on this PC, contact the maker, since the audio jack or sound chip may be faulty.
💡
Need a bigger reset?

If you decide to reset the whole PC, see our guide How to Fix "Reset This PC" Not Working in Windows 11. Back up your files first.

🎯What success looks like: Another device or microphone shows where the fault is, and your microphone works after the reset or the repair install.
↪️If it fails: If your PC cannot record from any microphone, the audio hardware is probably faulty. Contact the maker or a repair shop and mention what you tested.
08

Microphone Works Only in Some Apps

If Windows hears you but one app does not, work through these checks:

  1. Run the app's own test. Teams, Zoom and Discord all have a microphone test. If it shows your voice, the problem is the meeting settings.
  2. Pick the microphone inside the app (Fix 6). Apps do not always follow the Windows default.
  3. Check the three Privacy switches in Settings → Privacy & security → Microphone (Fix 3).
  4. Close other apps that may hold the microphone, and turn off exclusive mode (Fix 7).
  5. Browsers: allow the microphone for the website in the address bar and in the browser's site permissions.
  6. Remote Desktop or a virtual machine: turn on audio recording for the session or the VM (Fix 6).

Frequently Asked Questions

Why is my external microphone not working in Windows 11?
Usually the microphone is muted, plugged into the wrong jack, disabled, not selected as the default input, blocked by privacy settings or affected by a driver problem. Work through the connection, Sound settings and Privacy settings first, then check the driver.
Why does Windows 11 not show my external microphone?
The device may be disabled, the cable or port may be faulty, or the driver may be missing. Open the classic Recording tab with mmsys.cpl, show disabled and disconnected devices, and enable your microphone (Fix 4). If it is still missing, check Device Manager (Fix 9).
How do I enable an external microphone in Windows 11?
Open Settings → System → Sound and choose the microphone under Input. If it is not listed, run mmsys.cpl, open the Recording tab, right-click the microphone, choose Enable and Set as Default Device.
How do I allow apps to use my microphone in Windows 11?
Open Settings → Privacy & security → Microphone. Turn on Microphone access, Let apps access your microphone and Let desktop apps access your microphone. Make sure the app you use is switched on in the list.
Why does my microphone work in Windows but not in Teams, Zoom or Discord?
The app keeps its own microphone choice or is blocked by Privacy settings. Set the microphone inside the app's audio settings, allow desktop app access in Windows Privacy settings, and close other apps that might hold the microphone (Fix 3 and Fix 6).
Why did my microphone stop working after a Windows update?
An update can change the audio driver, disable a device or reset permissions. Update or roll back the audio driver, check Privacy settings, and if needed uninstall the update (Fix 9 and Fix 11).
Why does my headset microphone not work in the 3.5 mm jack?
Many laptops have one combo jack that needs a headset plug with a microphone (usually three black bands). A mic-only plug needs a splitter or USB adapter. On a desktop, use the pink mic jack, and check the Realtek jack prompt (Fix 1 and Fix 10).
Why does my Bluetooth headset microphone not work in Windows 11?
Remove and re-pair the headset, then choose the Headset (Hands-Free) entry as the input in Sound settings. Bluetooth microphones use the Hands-Free profile, and sound quality drops while the mic is active (Fix 10).
Why does my USB microphone keep disconnecting?
A hub, a weak port, a bad cable or USB power saving is usually responsible. Plug it straight into the PC, try another port or cable and set USB selective suspend to Disabled in the power plan (Fix 10).
Why is my microphone too quiet in Windows 11?
The input volume or Microphone Boost may be low, enhancements may muffle the sound or the wrong format may be set. Raise the Input volume, adjust the Levels tab and try turning audio enhancements off (Fix 2 and Fix 7).
What does Allow applications to take exclusive control mean?
It lets one app take full control of the microphone, which can leave other apps without sound. Untick it on the microphone's Advanced tab in the classic Sound panel if two apps conflict (Fix 7).
Is it safe to restart the Windows Audio services?
Yes. Restarting Windows Audio and Windows Audio Endpoint Builder reloads the sound system. Your files are not touched. Save your work first because sound will pause for a moment.
How do I make Remote Desktop use my local microphone?
Before you connect, open Show options → Local Resources → Remote audio → Settings and choose Record from this computer under Remote audio recording. Then check the microphone inside the remote session.
Why does my microphone not work in a virtual machine?
A virtual machine does not use the host's microphone unless audio input is enabled for it and the USB microphone is passed through. Check the VM's audio and USB settings.
Are the steps the same for Windows 10 and for Dell, HP, Lenovo and Acer laptops?
The ideas are the same on Windows 10, but menus differ, for example Privacy settings and the Sound page. For Dell, HP, Lenovo, Acer and other brands, the Windows steps are the same. What differs is the audio driver and software from the maker, so use the official support page for your model.
How can I tell whether the microphone or the PC is broken?
Test the microphone on another PC or phone, and test a different microphone or USB headset on this PC. If the microphone fails everywhere, it is faulty. If every microphone fails on this PC, the audio hardware or Windows setup is the cause (Fix 12).
When should I replace the microphone or get repair?
Replace the microphone, cable or adapter if it fails on other devices. Contact the maker or a repair shop if every microphone fails on your PC after a repair install.

Bottom line

Most external microphone problems in Windows 11 come down to the connection, the wrong default input, blocked privacy access, a disabled device or an audio driver problem. Check the plug and mute switch, choose the microphone under Input, allow microphone access, enable the device, set it inside your app, and restart the audio services. Then update or reinstall the driver. If the microphone fails on other devices too, replace it.
