Disable Microphone Auto Adjustment

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 reduces volume artificially, above artificially increases it).

 

Teams 'helpfully' automatically adjusts my volume. To 100%. Blowing my mic out, and making it utterly unusable. As far as I can tell, there is no way to disable this in the UI. Again, I'm on Windows 10 Pro, and I've disabled applications taking exclusive control in the microphone settings. This setting honestly does not seem to do anything at all in Windows 10, but that's a different story.

 

First, Teams absolutely needs the ability to disable auto-adjustment. It's utterly basic functionality which is necessary for anybody with a real mic.

 

But, in the meantime, is there any way I can disable auto-adjustment via a registry change?

 

Thanks.

  • 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.
