Ok, I'm back after researching and trying some things a bit more.

This is definitely possible entirely within pulseaudio. I'll go over the
basic concepts here, then show an example.

Now you can begin playing music, and in the Playback tab of pavucontrol
move the music playback to the VirtualMixer.
I got this far in following your instructions but got stumped on that last
part about moving the music playback to the VirtualMixer. This screenshot
shows my options for where to direct the Rhythmbox output:

If I select VirtualMixer, playback of the music continues but I can no
longer hear it. Is there a way for me to also hear it through my own
speakers/headset?
This is possible, but adds some complexity to the setup. To hopefully
make this easier to follow, I've made a little flowchart of all the
components:

Remember that pulseaudio draws a distinction between sources and sinks,
and normally doesn't allow you to route a source to sink or vice-versa.
So source components have a rounded face, and sink components have a
pointed face.
Certain endpoints are "exclusive," meaning that they can only have one
thing connected to or from it. These points have a grey shading to
indicate that property.
Modules with a thick border are real hardware. Modules with a thin
border are software. The dotted line around "auto monitor" refers to the
fact that it is auto-created when a virtual sink is created.
The thick lines connecting modules are the routings within Pulse. These
routings can all be modified in realtime within pavucontrol.
Hopefully this makes enough sense to help you to augment your script.
For comparison, here's the flowchart for my original suggestion that
does not let you monitor the music:

Hi All,
I was finally able to get this work! Thanks to the help of Sean as well
as following some of the steps on this site[1], I was finally able to
pipe BOTH my microphone AND the music from Rhythmbox to Jitsi while also
being able to hear BOTH the music and the incoming video conference
audio on my headphones! That site also referenced a helpful Stack
Exchange post[2] which also led me to this GitHug repository[3] which
contained a sample script[4] which I modeled to create my own[5].
My pavucontrol settings can be found here[6].
Still lots to learn now about how to improve latency, etc. but feels
good to have finally solved this.
Thanks again to Sean and everyone on this list who chimed in to help!
Samir
