What you should see: Your connected microphone should appear under Input. If it is missing, check the disabled-device and troubleshooting steps below.

How to View All Audio Input Devices in Windows 11

Before changing settings, check which microphones Windows 11 actually detects.

Check the Input List

Go to:

Settings > System > Sound > Input

Review the available devices and select the microphone you want to configure.

When a microphone is connected but does not appear, it may be disabled or there may be a driver problem.

Check the All Sound Devices Page

Some Windows 11 version 25H2 builds include an All sound devices page.

  1. Open Settings > System > Sound.
  2. Select All sound devices when it is available.
  3. Review the listed input and output devices.
  4. Check the live volume indicator beside an input device to see whether the microphone is detecting sound.
  5. Use the available controls to configure the device.

The supplied data notes that this feature has rolled out gradually, so it may not appear on every Windows 11 installation. If you do not see All sound devices, continue using the regular Input section.

Important: If a microphone works in one environment but not in a desktop application, check Let desktop apps access your microphone before changing other settings.

How to Set a Different Input Device for Specific Apps in Windows 11

Your Windows 11 default microphone does not always determine which microphone an application uses. Some applications provide their own input selector.

Choose the Microphone Inside the App

The supplied examples include:

  • Microsoft Teams: Settings > Devices > Microphone
  • Zoom: Settings > Audio > Microphone
  • Discord: User Settings > Voice & Video > Input Device
  • OBS Studio: Audio settings and input sources

How to Troubleshoot Common Windows 11 Microphone Problems

Default Microphone Keeps Changing

Connecting new audio hardware can cause Windows to reassign the input. Set the preferred microphone as both Default Device and Default Communication Device, then check Properties > Advanced when an application is overriding the selection.

Microphone Is Selected but No Sound Is Detected

Check Settings > Privacy & security > Microphone, confirm microphone access is enabled for the application, and then check Input volume and any physical mute control on the microphone or headset.

Input Volume Is Too Low Even at Maximum

Open mmsys.cpl > Recording > Microphone Properties > Levels and check for Microphone Boost. The supplied source suggests adding +10 dB or +20 dB and retesting where the option is available. USB microphones with a built-in preamp may not provide this Windows control.

Microphone Has Echo or Feedback

Open the microphone properties through mmsys.cpl and select the Listen tab.

Make sure Listen to this device is unchecked when it is creating a feedback loop. You can also use headphones or enable Acoustic Echo Cancellation under Enhancements when that option is available.

Crackling or Noisy Audio After Updating to Windows 11 25H2

The supplied source identifies this as a potential issue, particularly on systems using Realtek audio.

Start with the audio driver. You can roll it back or check:

Settings > Windows Update > Advanced options > Optional updates

If necessary, the supplied troubleshooting procedure also describes temporarily selecting the generic High-Definition Audio Device (Microsoft) driver through Device Manager to determine whether the problem is related to the installed driver.

Microphone Sounds Robotic or Muffled After a Windows Update

Updates can change microphone-related settings. Recheck Settings > Privacy & security > Microphone, then open the microphone properties through mmsys.cpl and review Enhancements and Default Format. The supplied source specifically recommends checking whether enhancements have been re-enabled after an update.

Restart Windows Audio Services

If the microphone still does not appear after checking permissions and drivers, restart the Windows audio services.

  1. Press Windows + R.
  2. Enter services.msc.
  3. Find Windows Audio.
  4. Double-click it.
  5. Click Stop.
  6. Wait about five seconds.
  7. Click Start.
  8. Also restart Windows Audio Endpoint Builder.

The supplied source recommends checking that both services use Automatic startup.

You can also restart Windows Audio through an elevated Terminal or Command Prompt:

net stop audiosrv && net start audiosrv

After the service restarts, check Settings > System > Sound > Input again.

How to Manage Bluetooth Audio Input Devices in Windows 11

Bluetooth headsets can behave differently from wired microphones because they use audio profiles that change depending on whether microphone input is active.

Select a Bluetooth Microphone

  1. Open Settings > Bluetooth & devices.
  2. Make sure the headset is paired and connected.
  3. Go to Settings > System > Sound > Input.
  4. Select the Bluetooth headset as your input device.
  5. If it does not appear, open mmsys.cpl > Recording and check for disabled devices.

These steps follow the Bluetooth-specific workflow in the supplied data.

Why Bluetooth Audio Quality Can Change During Calls

Bluetooth can use A2DP for higher-quality stereo output and HFP/HSP for hands-free microphone input. When the microphone is active during a call, the headset may switch to the hands-free profile, which can noticeably reduce playback quality.

Check Bluetooth Microphone Format

If you need to configure the Bluetooth microphone further:

  1. Open mmsys.cpl.
  2. Select Recording.
  3. Right-click the Bluetooth headset.
  4. Choose Properties > Advanced.
  5. Set Default Format to the highest supported sample rate; the supplied source notes that this is usually 16 kHz for Bluetooth microphones.

In the Playback tab, the supplied source recommends using Stereo (A2DP) for music and accepting the HFP switch when microphone input is needed during calls.

If a Bluetooth microphone keeps disconnecting or shows lag, check the headset connection, reduce wireless interference, or update the Bluetooth adapter driver through Device Manager > Bluetooth.

How to Reset Audio Settings in Windows 11

When several sound settings have been changed and you want to restore the relevant mixer settings to their defaults:

  1. Open Settings.
  2. Go to System > Sound.
  3. Select Volume mixer.
  4. Scroll to the bottom.
  5. Click Reset.

This restores the available Volume Mixer settings to their defaults.
