OK, all of this suggests that the file did not record correctly. And
after some experimentation myself, it seems like this is a known bug:

Sean,
What's the difference between parec and pacat? The former looks like the
eqivalent to parecord or paca -r.
Oh. When I started having issues I upgraded pavucontrol from -3.0 to -4.0.
The last time the AT2500 worked as expected was with 3.0 installed.
It seems like the wav format does work, so give this variant a try:
$ pacat -v -r --file-format=wav /tmp/sounds.wav
and
$ pacat -v -p --file-format=wav /tmp/sounds.wav
So I tried these with 4.0 and still no sound.
$ pacat -v -r --file-format=wav /tmp/sounds.wav
Opening a recording stream with sample specification 's16le 2ch 44100Hz' and
channel map 'front-left,front-right'.
Connection established.

Then I restored version 3.0 and saw the same results.
I have some music files in .wav format. I just played one (pavucontrol
version 3.0) using 'pacat -v -p --file-format=wav s-and-g.wav'.
pavucontrol's Playback tab's VU meter moved as the song came out of the
speakers.
Darn! What else can I do to find why what's recorded by the mic won't play?
My Scarlett solo is an older gen, so it doesn't have an "air" switch. I
was curious what that was, so here's what their docs have to say:
Lol, it's just a fixed EQ curve. This should not be the cause of your
issues, though feel free to use it if you like the tone it produces.
Yes, I have the Gen3 since I bought it mid-last year. I looked up 'air' in
the manual and saw it would really not apply to speech but would to music.
Regards,
Rich
