Thanks for the note. I wanted to give a quick update on my situation.
I'm not familiar enough with JACK yet to determine whether or not your
advice still applies. If is still does, I'm not sure I follow
everything so may have some follow up questions.

Again, I'm trying to combine the music playing from Rhythmbox with my
voice from the microphone and send that out to a meeting service like
Jitsi (or Zoom).

With Rhythmbox running and playing music, I open up qjackctl and the
"Connections" window looks like this:

In PulseAudio Volume Control, the "Playback" tab looks like:

The "Output Devices" tab looks like:

The "Input Devices" tab looks like (2 screenshots):

With this setup AND with JACK running, I can hear the music through my
speakers! (Minor victory, but I'll take it!)

  I just need help on:

How to I combine my voice from the microphone and then have that serve
as the "input" to Jitsi or Zoom.

Is that where these mixers come in or can I do through directly through
qjackctl and PusleAudio Volume Control?
