Microsoft Teams includes a built-in noise suppression feature designed to reduce background sounds like typing, fan noise, or conversations during calls. When it works correctly, it significantly improves call quality. However, some users find that noise suppression is not working, leading to distracting background noise during meetings.
This issue can occur due to incorrect settings, outdated app versions, microphone configuration problems, or system-level audio conflicts. Since noise suppression relies on both software processing and proper input settings, even small misconfigurations can affect its performance.
In this guide, we’ll walk you through effective methods to fix Microsoft Teams noise suppression not working and restore clear audio during calls.
How to Fix Teams Noise Suppression Not Working
Before applying the fixes below, it’s important to ensure that noise suppression is actually enabled in Microsoft Teams and that your microphone is properly configured. The methods below are arranged from basic checks to more advanced troubleshooting steps.
1. Enable Noise Suppression in Teams Settings
The feature must be turned on manually in Teams.
- Open Microsoft Teams.
- Click your profile picture in the top-right corner.
- Go to Settings > Devices.
- Under Noise suppression, select Auto or High.
If it’s set to “Off,” Teams will not filter background noise.
2. Check Microphone Selection
Using the wrong microphone can affect noise suppression.
- Open Teams Settings > Devices.
- Under Microphone, select the correct input device.
- Speak and check the input level indicator.
Ensure Teams is using your intended microphone.
3. Update Microsoft Teams
Outdated versions may have bugs affecting audio features.
- Open Microsoft Teams.
- Click your profile icon.
- Select Check for updates.
- Install any available updates.
Updates often fix audio-related issues.
4. Disable System Audio Enhancements
Conflicting enhancements can interfere with Teams processing.
- Right-click the sound icon in the taskbar.
- Select Sound settings.
- Click More sound settings.
- Select your microphone and click Properties.
- Go to the Enhancements tab.
- Check Disable all enhancements and apply changes.
This allows Teams to handle audio processing directly.
5. Adjust Microphone Input Levels
Incorrect levels can reduce noise suppression effectiveness.
- Open Sound settings.
- Select your microphone under Input.
- Adjust the input volume to a balanced level (not too high).
Proper levels help Teams distinguish between voice and noise.
6. Close Background Apps Using Microphone
Other apps may interfere with audio processing.
- Press Ctrl + Shift + Esc to open Task Manager.
- Close apps using the microphone (e.g., recording tools, other communication apps).
- Restart Teams.
This prevents conflicts between applications.
7. Check Permissions for Microphone Access
If Teams lacks permission, features may not work correctly.
- Press Windows + I to open Settings.
- Go to Privacy & Security > Microphone.
- Ensure Microphone access is enabled.
- Make sure Teams is allowed to use the microphone.
Permissions are essential for proper functionality.
8. Use a Different Microphone
Some microphones may not work well with noise suppression.
- Try switching to a different microphone (USB or headset).
- Test audio in Teams.
Higher-quality microphones often yield better results.
9. Reinstall Microsoft Teams
If the issue persists, reinstalling can fix corrupted files.
- Press Windows + I and go to Apps > Installed apps.
- Find Microsoft Teams and uninstall it.
- Download the latest version from the official website.
- Install and sign in again.
Reinstallation ensures a clean setup.
Conclusion
Microsoft Teams noise suppression not working can lead to poor call quality, but the issue is usually caused by simple misconfigurations or outdated software. By ensuring the feature is enabled, checking microphone settings, and updating the app, you can quickly restore proper functionality.
The methods outlined in this guide cover both basic and advanced fixes, helping you achieve clear and distraction-free audio during meetings.
