Detailed Fixes for “Microphone doesn’t work in Windows 10”

1. Microphone is muted or volume too low

Why this causes the problem:
A muted mic or very low input level prevents Windows and apps from detecting or recording audio.

Step-by-step solution:

  1. Right-click the speaker icon on the taskbar and choose Open Sound settings.
  2. Under Input, open Device properties for your microphone and increase the Volume/Levels.
  3. For advanced control, open Control Panel > Hardware and Sound > Sound, go to the Recording tab, select your mic and click Properties > Levels. Increase the slider and unmute if needed.
  4. If your headset has a hardware mute switch, ensure it’s unmuted.
    Notes/tips: Use the Test your microphone input bar in Settings > System > Sound to see live input.

2. Wrong default device selected

Why this causes the problem:
Windows sends input to the default device; if the wrong device is default, your mic appears dead.

Step-by-step solution:

  1. Go to Settings > System > Sound.
  2. Under Input, choose the correct device from the Choose your input device dropdown.
  3. Or open Control Panel > Sound, go to Recording, right-click your device and choose Set as Default Device and Set as Default Communication Device.

Why this causes the problem:
Windows blocks apps from accessing the microphone if permissions are denied.

Step-by-step solution:

  1. Open Settings > Privacy > Microphone.
  2. Turn on Allow access to the microphone on this device and Allow apps to access your microphone.
  3. Scroll down and toggle access for the specific app (Microsoft Store apps) and allow desktop apps (toggle Allow desktop apps to access your microphone if present).
    Notes/tips: For apps like Skype and Zoom, also check their internal audio/input settings.

4. Microphone disabled in Device Manager or Sound control

Why this causes the problem:
If Windows has disabled the mic or it’s turned off, it won’t accept input.

Step-by-step solution:

  1. Right-click Start and open Device Manager.
  2. Expand Audio inputs and outputs, right-click your microphone entry and choose Enable device (if disabled).
  3. If it’s missing, in Device Manager click Action > Scan for hardware changes.
  4. Also open Control Panel > Sound > Recording, right-click inside the list and ensure Show Disabled Devices and Show Disconnected Devices are checked; enable the mic if shown.
    Notes/tips: Some laptops use a keyboard function key to enable/disable microphones; check your laptop manual.

5. Faulty or loose physical connection

Why this causes the problem:
A loose jack, bad USB connector, or damaged cable interrupts the audio signal.

Step-by-step solution:

  1. Unplug the microphone and plug it into a different port (front vs rear jack, another USB port).
  2. Inspect the connector and cable for damage.
  3. Test the mic on a phone or another PC to confirm it works.
  4. If using a USB mic, try a USB port directly on the PC (avoid hubs) and try different USB types (2.0 vs 3.0).
    Notes/tips: Dirt in the jack can block contact; compressed air can clean it safely.

6. Incorrect jack or TRRS wiring (headset wiring mismatch)

Why this causes the problem:
Headsets with combined headphone/mic plugs (TRRS) may not match separate mic/headphone ports (TRS), causing no mic signal.

Step-by-step solution:

  1. Identify your headset plug: TRS (three segments) is for stereo only, TRRS (four segments) includes mic.
  2. If PC has separate mic and headphone jacks, use a TRRS-to-dual-TRS splitter (mic + headphone).
  3. Alternatively, use a USB audio adapter that accepts a single TRRS plug.
    Notes/tips: Many laptop ports expect CTIA wiring; old headsets may use OMTP wiring — adapters can fix wiring differences.

7. Outdated or corrupt audio drivers

Why this causes the problem:
Bad drivers prevent Windows from talking correctly to audio hardware.

Step-by-step solution:

  1. Open Device Manager > Audio inputs and outputs.
  2. Right-click the microphone or sound device and choose Update driver > Search automatically for drivers.
  3. If automatic update fails, visit the laptop or audio device manufacturer’s website, download the latest driver and install it.
  4. To reinstall: in Device Manager, right-click the audio device, choose Uninstall device, then restart the PC to let Windows reinstall the driver automatically.
    Commands: Use sfc /scannow in an elevated Command Prompt if you suspect system file corruption affecting drivers.
    Notes/tips: For Realtek audio, install the Realtek HD Audio driver package from the PC maker or Realtek site.

8. Windows Audio service stopped

Why this causes the problem:
The Windows Audio service handles sound; if stopped, devices won’t function.

Step-by-step solution:

  1. Press Windows + R, type services.msc and press Enter.
  2. Find Windows Audio, right-click and choose Restart. If it’s not running, choose Start.
  3. Also check Windows Audio Endpoint Builder and ensure it’s running.
    Notes/tips: If services won’t start, run sfc /scannow and check for system updates.

9. Exclusive mode or audio enhancements conflict

Why this causes the problem:
Some apps take exclusive control of the microphone or audio enhancements cause incompatibility.

Step-by-step solution:

  1. Open Control Panel > Sound, go to Recording, select your mic and click Properties.
  2. Under the Advanced tab, uncheck Allow applications to take exclusive control of this device.
  3. Go to the Enhancements tab (if present) and check Disable all enhancements or deselect enhancements that may interfere.
    Notes/tips: Some pro audio software requires exclusive mode — try toggling the setting to test.

10. Bluetooth microphone pairing issues

Why this causes the problem:
Bluetooth profiles sometimes default to the wrong mode (A2DP vs Hands-Free) or pairing fails.

Step-by-step solution:

  1. Open Settings > Devices > Bluetooth & other devices.
  2. Remove the headset (click device > Remove device), then pair it again.
  3. After pairing, select the Bluetooth device as input in Settings > System > Sound.
  4. If audio only works in the headset as output, ensure the Hands-Free AG Audio or Headset profile is used in Control Panel > Sound.
    Notes/tips: Bluetooth mics often have lower quality unless using the correct hands-free profile.

11. App-specific settings or conflicts

Why this causes the problem:
An app may be set to use a different input or block access; other apps may monopolize the mic.

Step-by-step solution:

  1. In the app (Zoom, Skype, Discord), open its audio or input settings and choose the correct microphone.
  2. Close other apps that might use the mic (voice recorders, browser tabs with mic access).
  3. Use Settings > Privacy > Microphone to see recently used apps and check permissions.
    Notes/tips: Restarting the PC closes hidden processes that might hold the mic hostage.

12. Hardware failure

Why this causes the problem:
Internal mic elements or wiring can fail with age, drops, or moisture exposure.

Step-by-step solution:

  1. Test the microphone on another device (phone, tablet, or another PC).
  2. Try a different microphone on your PC to confirm the PC’s hardware is okay.
  3. If the mic fails on multiple devices, replace it; if other mics fail on your PC, consult repair or check motherboard audio hardware.
    Notes/tips: On laptops, an internal mic can be replaced by a technician; external USB mics can often be sent for warranty replacement.
