I've been hacking it in the past to solve some bluetooth issues and I know
there were issues before especially with the loopback module. However in
12.2 most must have been solved. I use the 12.2 with stretch and I saw that
12.x is default in buster. I think it was 12.5.

I did now

$ pactl load-module module-loopback
29
$ pactl list | grep loop
        Name: module-loopback
        Driver: module-loopback.c
        Driver: module-loopback.c

so with 12.2 it works just fine. I recommend trying 12.2 on stretch or
buster.
