    Workaround on macOS: create an aggregate device to "mask" the gain settings from Teams.

    Steps:

    1. Open 'Audio MIDI Setup' application
    2. In the left pane, click + symbol and choose Create Aggregate Device
    3. Ensure that the new aggregate device is selected in the left pane
    4. In the main window area, select the 'Use' checkbox for your real input device
    5. Select the real input device from the left pane and set the Master Stream input gain correctly
    5. Optionally rename the newly created aggregate device by clicking its entry in the left pane
    6. Quit & restart Teams application
    7. In Teams, choose the newly created aggregate device as the microphone device

    Because the aggregate device does not have a gain setting, Teams cannot f* it up.

I was working thru this same issue of MS Teams auto adjusting my volume to the max while on a Teams call. Use this website https://support.apple.com/en-us/HT202000 to set up an Aggregate Device on your Mac, then choose that device as your input source for the Teams call and it will no longer auto adjust the input gain. #gamechanger
