I just checked the Jitsi Meet using Chromium (they recommend
Chrome/Chromium, apparently Jitsi uses some newer streaming standards
that Firefox either doesn't fully support or is just simply too slow).
For microphone, it offers my USB headset, USB audio, Builtin and
Pulseaudo JACK source. Which I remember I do have Pulseaudio set up here
feeding to JACK sink. Output include the preceding plus PA Jack sink.

I think that means you could have either your streaming audio going into
it, or your microphone, but not both.
