If your microphone volume keeps jumping up and down on its own in Windows 11, something is adjusting it automatically. Usually it’s a calling or chat app (Teams, Zoom, Discord, Skype or a browser) using automatic gain control, but Windows’ own settings and audio driver software can do it too. The fix is to stop apps from taking control of the mic and turn off each app’s auto-adjust option. This guide walks through all of them.
Quick Answer
Open Control Panel > Sound (or Settings > System > Sound > More sound settings), go to the Recording tab, double-click your microphone, and on the Advanced tab uncheck Allow applications to take exclusive control of this device. Then turn off automatic mic adjustment in apps like Zoom, Teams and Discord.
Step 1: Stop Apps Taking Control of the Microphone
- Press Windows key + R, type mmsys.cpl, and press Enter (or go to Settings > System > Sound > More sound settings).
- Click the Recording tab.
- Double-click your microphone.
- On the Advanced tab, uncheck Allow applications to take exclusive control of this device.
- On the Levels tab, set the microphone level you want, for example 80.
- Click Apply and OK.
This blocks many apps from changing the Windows mic level. Some apps still apply their own gain to the audio they send, so continue with the app settings below.
Step 2: Turn Off Auto-Adjust in Your Apps
Zoom
Open Settings > Audio and uncheck Automatically adjust microphone volume. Then set the input volume slider manually.
Microsoft Teams
Click the three dots > Settings > Devices (or Devices in audio settings) and turn off Automatically adjust mic sensitivity if your version shows it. Noise suppression settings are separate and don’t change the volume.
Discord
Go to User Settings > Voice & Video. Scroll to Advanced (or Voice Processing) and turn off Automatic Gain Control. Adjust Input Volume manually.
Skype
Go to Settings > Audio & Video and turn off Automatically adjust microphone settings.
Browsers (Google Meet and web apps)
Web apps use the browser’s built-in audio processing, which can include automatic gain control, and most don’t offer a switch to turn it off. Unchecking exclusive control in Step 1 prevents the Windows level from changing, even if the app still processes the audio. Using the desktop app of a service often gives you more control.
Step 3: Check Windows Sound Settings
- Open Settings > System > Sound and click your microphone under Input.
- Set Audio enhancements to Off (or open Advanced and turn off Enable audio enhancements).
- Set the Input volume to your preferred level.
Step 4: Check Audio Driver Software
Many laptops include audio software (such as Realtek Audio Console, Dolby Access, Waves MaxxAudio or manufacturer utilities) with features like “voice leveling,” “noise suppression” or “auto volume.” Open the app from the Start menu and turn those features off for the microphone. Updating the audio driver from your PC maker’s support site can also fix buggy behavior.
Still Changing? Try These
- Close background apps that use the microphone (check the mic icon in the taskbar to see which apps are listening).
- Headset software: gaming headsets often have their own app with auto gain; turn it off there.
- Run the audio troubleshooter: Settings > System > Troubleshoot > Other troubleshooters > Recording Audio (or Get Help on newer builds).

Frequently Asked Questions
Why does my mic get quieter during calls?
The calling app is lowering the gain to prevent clipping or background noise. Turn off its automatic adjustment and set the level yourself.
Does this work in Windows 10?
Yes. The Sound control panel steps and app settings are the same in Windows 10.
Will turning off auto-adjust make my audio worse?
Not if you set a good fixed level. Speak normally and aim for the level meter to peak around two-thirds, without hitting the top.
Summary
- Uncheck exclusive control in the microphone’s Advanced properties.
- Turn off auto-adjust or automatic gain control in Zoom, Teams, Discord and Skype.
- Turn off audio enhancements in Windows sound settings.
- Disable voice leveling in audio driver software.
