Turns out, there was an Unrelated Issue, all the way back when I installed Stretch. I made an /etc/fstab error, causing me to not have a Swap Partition.
So I had a Memory Low situation, causing programs on one Console to stop, when I switched Perspective.
When I fixed my Memory and Swap errors, my problem is solved.
Sorry for the length of time between Replies: I'm pretty busy.
And thank you, Jonathan, for putting me back onto troubleshooting the actual issue.

I would research systemd (and/or PAM) "sessions, and "multi seat
support", which is my best guess as to what's happening. I don't think
the process is being stopped, but you are prevented from hearing it's
audio because that VT is no longer marked as an active local session.
I plan to learn SystemD as best I can. It's here to stay, so make the best of it.
There's some details here

Thank you. Very informative!
