[AudioI] Zero card stopped working -- will order new hardware to troubleshoot

Thanks, Matt --
First regarding your helpful comments and questions:
1) I am running RaspiOS lite on the pi zero. It doesn't seem to have
pulseaudio, unless it's installed under some other name. ("sudo apt-get
remove pulseaudio" reports it's not installed)
2) the alsamixer settings were correct and had worked before.
3) I had tried the line bypass but couldn't know whether the board audio
chain was at fault or whether it was not being set by the software via the
pi.
I had fastened on the dmesg not including the "mapping ok" line as an easy
diagnostic for whether things were working. But in fact this seems to
have been introduced by some update (via sudo apt-get update/upgrade) after
the 1/21/2021 OS release -- a clean install showed success by this criteria
with the new card and I think also the old one but a clean install followed
by update/upgrade reverted to the previous behavior with the new card...
This was true on a Pi Zero and a previously lightly used model 2B that I
had around. I'll attach the dmesg results from the two software versions.
I don't know enough to decipher them.
Once I got over the distraction of the software and the dmesg reports, I
found that in fact the audioinjector zero card had been damaged -- the old
pi zero records audio with the new card with either version of the OS, but
the old card doesn't work.
I am not out of the woods yet. I have a new problem and have narrowed down
the current version of a previous one.
Both problems relate to using an approach I found somewhere on the
internet for setting up a remote mic. I am using it to send ambient
(nature) sound from a remote outside location to my room audio system so we
can hear outside noises without opening the window when it's 20 below.
This requires a high dynamic range and low noise floor to hear distant
birds, coyotes, etc. I use a stereo powered condenser mic intended for a
camera and a 2 stage opamp preamp (Rod Elliott p88 )
This is what I was using for the sound transport over wifi and ethernet:
arecord -c 2 -f dat -t raw - | ssh pi@[local ip address] aplay -c 2 -f dat
-t raw -Dhw:sndrpihifiberry -
The new problem is that somehow there is more than a one second delay in
the transported sound compared to what is being recorded. Presumably it's
made a large fifo buffer for some reason. Perhaps this has to do with
changes on the receiving pi that I made when trying to diagnose the earlier
problem.
The persistent problem that I thought I had licked is that there is a
tickatickaticka noise in the sound. I thought this was from the
wireless and by separating the mic and preamp from the Pi and
audioinjector i did seem to get the noise down to zero -- based on what I
was hearing via the audioinjector headphone jack and the line bypass. But
the noise reappeared when using arecord (and was even worse when I tried
"arecord ... - " without piping it anywhere. I could hear the noise in
the audioinjector headphone output as well as in the transported sound.
Putting the audioinjector several inches away from the pi with a piece of
grounded aluminum between the two did not reduce the noise. Clearly I
need to investigate further but this seems to be either some sort of
digital artifact or rf feedback from the PI's digital operations back into
the audioinjector card.
I may try the sox equivalents instead of aplay and arecord -- but I
haven't had great luck getting sox to run yet.
