From your sender log, this line tells me a lot:
2020-10-26 17:23:58,053 - openob.node.node-2.link.test-link.tx - DEBUG -
Level: -350.00
This suggests to me that maybe the Linein on your sender's sound card is
muted, perhaps turned all the way down, or maybe if there are more then
one input options on that card then the wrong input is selected
Do an:
alsamixer -c X
Where X is the audio card number. If you're not sure which one it is,
try a:
cat /proc/asound/modules
And you should be able to figure out what the hardware number of your
sound card is for your UAC202
Then once in alsamixer go to the Input screen (it is one of the F keys
to access, I can't recall which one right now and I'm not at a Linux box
to check). Make sure the needed input is selected and the level is up.
Also, if you are running Pulseaudio on those computers then kill it.
You'll probably have to activate the autospawn=no setting in the
/etc/pulse/client.conf file and then kill pulseaudio (or just reboot)
