My experience with Jitsi is that its audio input is limited to two
sources: Whatever microphone you have connected to your computer, and
your chosen YouTube URL (if you use Jitsi's option to stream a YouTube
URL). It lets you stream a YouTube URL, but that seems to take over the
Jitsi screen. I think at that point maybe you could talk in your
microphone and have it audible over the YouTube stream... but I don't
know, I haven't tried it.

I tried to find a way to stream just audio from my music library here
(mplayer playing through JACK) but couldn't find a way to get Jitsi to
take JACK as an input. The only options I saw were hardware ones.

I don't use Pulseaudio, maybe it could be set up to get around Jitsi's
idea of "hardware"?

Maybe play your music to a channel connected to an external mixer,
connect your regular microphone to a different channel on the mixer,
then connect that output to a microphone in on your compute?

I don't know, just guessing. Hope it helps!
