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.

beizs I have had the same issue and found the 'virtual audio cable' is a solution. I did not like however that my Mic was 'hot' (on) all the time with 'virtual audio cable' and the need to configure additional driver settings.

 

I have since switched to 'NVIDIA Broadcast' instead of virtual audio cable. With NVIDIA Broadcast there is no audio configuration mapping to do, just select your (Rhode) Mic in NVIDIA Broadcast and in MS Teams choose 'Microphone (NVIDIA Broadcast)'.

 

You will need a supported NVIDIA card to use the software. There are also some great audio and camera features in this application for streaming and conferencing too.
