Hi, @Paul Spencer
Have you already tested whether Windows itself can hear the microphone?
Go to "Settings > System > Sound > Input", select your microphone, then choose "Start test" and speak normally. If Windows detects your voice there, the microphone itself is working.
Also check "Settings > Privacy & security > Microphone" and make sure "Microphone access" and "Let desktop apps access your microphone" are turned on. Microsoft lists these settings as required for microphone access:

If the issue still persists, to help narrow down the issue:
- When you test the microphone under "Sound > Input", does Windows detect any sound?
- Press Windows key + R, type winver and press Enter. What Windows version and build are shown?
