Forgot to say that originally on Windows I also had trouble getting audio into
the captured video. It was not fixed until I installed the driver that publishes
as "virtual-audio-capturer" to ffmpeg.
Unfortunately it is a Windows only open source driver...
Available here:

Question:
Is there some comparable driver available for Ubuntu 20.04?
