You do not say what distribution you are running on that Thinkpad.
Xubuntu 18.04.
So, I am going to guess that you are using pulse audio and have pavucontrol, and
pulseaudio-utils installed.
If that is the case try this guide:
https://ro-che.info/articles/2017-07-21-record-audio-linux
It recommends trying:
~$ pacmd list-sources | egrep '^\s+name: .*alsa_input'
name: <alsa_input.pci-0000_00_1b.0.analog-stereo>
~$ pacmd list-sources | egrep '^\s+name:.*\.monitor'
name: <alsa_output.pci-0000_00_1b.0.analog-stereo.monitor>
If you use pulse audio, alsa, ... just about anything and you are fan of ffmpeg
- you could try:
Check supported ffmpeg devices:
ffmpeg -devices true -f dshow -i dummy

if you use PA - use pavucontrol to select microphone and set its gain:
ffmpeg -f pulse -i default output.mp3
ffmpeg -f pulse -i default output.wav
if you use alsa - use alsamixer to select microphone and set its gain:
ffmpeg -f alsa -i default output.mp3
ffmpeg -f alsa -i default output.wav
If your distro is really old and still uses oss - just replace alsa/pulse with
oss in ffmpeg options.
Hope it helps,
I'll give those a try later on. I've also got another box that doesn't
seem to have a problem recording with Audacity. It's a few more pieces
to carry around, but I think it works right, so I'll be trying that,
too. I've still got a few weeks before it needs to work.
Thanks for the advice.
