We offer some ideas that might help you resolve audio issues during a call:

• Verify audio permissions: Make sure Teams has permission to access the microphone and speakers in your device or browser settings.
• Check device settings in Teams: Open Teams and click on the three dots to the left of your profile picture at the top. Select Settings and then Devices. Ensure the correct microphone and speakers are selected in the dropdown options. Note that the device names can be somewhat confusing; they might look something like this:
  
• Noise cancellation issues: Although it's a very effective feature, in some cases it can cause interruptions in the conversation (when using the microphone of a camera, for example). There are three levels:
  • Automatic (default): Teams optimizes a certain level of noise suppression and is best for most situations.
  • High: Suppresses all background sound except for voice.
  • Low: Suppresses low levels of persistent background noise, like a fan or air conditioner. Use this option to play your choice of music for other meeting participants to hear, such as when waiting for a meeting to start.

In any case, disable noise suppression for high-fidelity microphones in a low-noise environment, like a quiet studio.

• Update Teams: Make sure you have the latest version of Teams installed, as updates may include improvements in features like noise cancellation.
• Update drivers: Ensure your microphone and speaker drivers are updated. You can do this through the Device Manager in Windows. Ask your center's IT Services for help if you have doubts about how to proceed.
• Test call: In Teams settings, select Devices and then make a test call to verify everything is working correctly. It's a good habit to perform the test when installing new devices.
• Troubleshooter: If all else fails, use the Windows audio troubleshooter to automatically detect and fix issues.
