My microphone is a USB Blue Spark. The mic itself has gain controls, and in Windows (10), it needs to be set to 50% or less, otherwise it starts to clip like crazy (50% is essentially baseline, below...

    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.

Had the same issue with my Rode USB mic.
Fixed it using VB-Cable, with this software the output of the microphone can be mirrored to a virtual device and Teams can be set up to use this virtual device. That way Teams does not see the Microphone directly and can't mess with it's level/gain.

 

Indeed not a great solution but it may help someone.

I would definitely prefer a switch in Team's settings to disable this "feature".
