Within GRUB sources (I downloaded it with git) you have a
util/spkmodem-recv.c file, and, as indicated in the comments in it, you
just need to compile it with “gcc -o spkmodem-recv spkmodem-recv.c”,
connect one end of the jack to the audio input (microphone) of your
computer (the one that is on and from which you will listen) and the
other on the audio output (headspeakers) of the computer that you will
boot with spkmodem module, then you run “parecord --channels=1
--rate=48000 --format=s16le | ./spkmodem-recv” (personally parecord
didn’t work so I used parec instead) and that will write on standard
output all the things about libreboot booting.
