    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.

    There is a simple fix to this. Nircmd will allow you to set the volume every 0.5 s.

    nircmd setsysvolume 65535 default_record
    nircmd loop 172800 500 setsysvolume 62000 default_record

        RichardHauer I agree it's a hack. The only fix is for Microsoft to create a flag so you can disable AGC from teams. Until they do this will enable you to use a microphone like blue yeti X without AGC messing up the sound.
