Reason

This can happen if sounds are played louder than your voice while automatic volume gain options in your voice apps or audio drivers are active. These options dynamically change your microphone volume in Windows. Voice apps like MS Teams have such options. They are called automatic volume gain, automatic gain control (AGC), smart volume or similar.

Solution

  1. Disable the automatic volume adjustment option in your voice apps or audio drivers. Look for names like automatic volume gain, automatic gain control, smart volume or similar.

The voice volume should be above 74 dB, otherwise certain voice applications may filter out played sounds misinterpreting them as background noise. If your measured voice volume is lower than 74 dB, it is recommended to increase the overall microphone volume in Windows.
