Teams: Disable Microphone Auto Adjustment – Technipages


Your microphone often seems to have a will of its own during Microsoft Teams meetings. That is to say, the app automatically adjusts the microphone volume to 100%. This issue is even more annoying if you have a susceptible mic that requires low gain.

How to Stop Teams from Adjusting Your Mic

Disable Exclusive Mode

Let’s start by denying Teams permission to fully control the microphone.

  1. Copy-paste mmsys.cpl in your Windows Search bar and press Enter.
  2. In the Sound window, click on the Recording tab.
  3. Then right-click on your microphone and select Properties.
  4. Under Exclusive Mode, uncheck the option that reads Allow applications to take exclusive control of this device.
  5. Unplug your microphone and restart your computer. Check if Teams still has full control over your microphone.

Use an Audio Management App

Many Teams users solved this microphone problem with the help of different audio management apps. Some used VB-CABLE Virtual Audio Device, while others installed Voicemeeter or the NVIDIA Voice app for background noise filtering.

Feel free to start with any app you want. Then tweak the settings to block Teams from messing with the volume.

VB-CABLE Virtual Audio Device

For example, let’s say you decide to install VB-CABLE Virtual Audio Device. Here’s how to set up the tool:

  1. Download the app from https://www.vb-audio.com/Cable/index.htm.
  2. Then extract and install the virtual audio cable driver.
  3. Restart your computer and go to Sound settings.
