It seems to be fairly common among Jamulus users to run a muted instance
of Jitsi (<https://meet.jit.si/whatever_you_want_to_call_your_room>) in
parallel.  If your Internet connection is even slightly sketchy, that
may not be advisable regarding audio quality.

I held a (German) talk about Jamulus at the Chemnitzer Linuxtage
yesterday.  Slides are linked from the talk site at
<https://chemnitzer.linux-tage.de/2021/de/programm/beitrag/120>.  The
video is not available yet from the conference site, but at least the
prerecorded bulk of the session (before the last slide and without Q&A)
can be seen at <https://youtu.be/Vn1f70IH-Es>.

And with echo compensation removing any feedback I did not realise that
the live part of the talk was too loud and clipped, and my session host
had such lousy audio equipment that he did not notice (or mind) either.
So I am not sure how bearable that part would be to listen to anyway.

Probably worth checking out the slides and if you think you can make
sense of those in spite of the language (or cannot make sense of those
in spite of the language), viewing the video might help.
