Installed microphone appears in Settings as disabled 9/0

In Windows 11 - Settings / Sound / All Sound Devices I have listed a Microphone Array, part of Lenovo FHD Webcam Audio. This shows as Disabled. Why ???
When I click on it and go to Properties it is set to "allow Apps and Windows to use this device for audio". That is, again, set to Allow. All the other settings make sense in terms of it should work, so why is it disabled?

The driver has been updated and is current. Windows 11 is current with updates. I have uninstalled and reinstalled the webcam, but it reinstalled as Microphone Disabled. The Windows Audio troubleshooter is no help. I have the same exact installation on another desktop running Windows 10 and have no issue with the same device. What in the Sam Hill is going on???

Let me add to the problem statement. Under Settings / Sound there is no Input Device chosen. If I select Add Device where it says "Pair a new input device" the machine never comes up with the Lenovo Web Cam to add. To me this makes no sense because, as I said in the original post, it does show under
System / Sound / All Sound Devices as a Microphone Array. It also shows under the Control Panel / Bluetooth and Devices / Devices as Lenovo FHD Webcam under Audio.
