Security, my friend! It you don't like the Fedora life-cycle, use
something LTS like CentOS.

I used the pulseaudio volume control GUI to select line as input. Then
$ pacmd list-sources
to find the number of the device with the description "Built-in Audio
Analog Stereo", which is '2' in my case. Then I put '2' as input here:
$ ffmpeg -f pulse -i 2 -c:a libmp3lame recorded.mp3
This records forever until you press 'q'. It uses some default settings
which may or may not be okay for you.
You should probably google for "capturing audio linux" to figure out
about alsa and pulseaudio if this doesn't work for you. ffmpeg supports
both if compiled to do so.
