How to spoof a microphone to a program?

I often need to join Zoom meetings where I am merely a participant (that is, listening only and not speaking).

Zoom lets you join without a webcam fine, but moronically requires you to have an audio input as well as output to use computer audio. This means if you have a speaker/headphones/earbuds, too bad, so sad – according to Zoom – unless you also have a mic connected to your computer.

This means that I need to dial in by telephone even though I have a perfectly functional audio output, which works but is not ideal.

There’s probably little chance of getting Zoom to use some common sense here, so I’m wondering how easy it would be to “spoof” the existence of a microphone to Zoom at the application layer from Windows, to make it complacent and let me use computer audio. I don’t need the spoofed mic to work, or actually do anything at all, but just be detectable by Zoom so that it’ll let me proceed.

Is there a way to do this, without physically connecting any hardware to the computer?
