Unfortunately for those of us without a mic, at the moment Zoom does not let you join and just listen.
Fortunately, though, there is an easy solution.
Virtual Audio Cable can create an input device to route computer audio as a “microphone”, allowing you to join the conference and listen.
All you have to do is Download and install the software and Zoom will recognize it as an input device without you having to have a hardware mic.
