I rarely have computer audio problems, it usually just works. But today I need to record voice and it does not do anything, pulse audio shows rear microphone plugged in and the level is turned up. aplay produces a test sound from the speaker and sound works as expected, just no mic audio.
This a recent Fedora-30 upgrade from F-29. I don't often need the mic so I don't know if this is an artifact of an earlier problem. I tried two mics, both are old, one is ancient, but I have used them in the past.
Any ideas welcome, Bob

do they work in a different computer? or if you boot from a stick with some other distro?

It's a configuration problem. If pulse sees the mic, then alsa has recognized it.
First thing, run alsamixer -c <card number> Then hit F4 to get to the capture screen. Make sure that the capture is turned on in alsa, and at a high enough level.
Then, if you don't have it installed already, install pavucontrol. Bring it up and play around with the default settings (last tab) for the mic until you can see waveforms for capture in the capture tab.
You could instead use arecord to try to capture some sound in a .wav file. I haven't done that for a long time, so you will have to read the man page, man aplay, to figure out how if you decide to do so.
Another alternative is to use audacity to capture the sound from the mic. It also allows configuration for direct record from alsa, I think. So, you could disable the card in pulseaudio, and use alsa directly if you just can't get pulse to record.
I agree with Stan. This seems like a config (or rather, routing) problem.
Also, what application are you attempting to record audio into?
Here's an overview of Linux sound I wrote for opensource.com: https://opensource.com/article/17/1/linux-plays-sound
It might help you troubleshoot.
