Solved! It turns out the bug was caused by two codecs conflicting with each other, or something like that. We got sound by adding the line
options snd-hda-intel probe_mask=1
to the file
/etc/modprobe.d/alsa-base
This should of course have been done automatically by ALSA but since this particular computer is not a "known buggy" device, ALSA doesn't know about it. Here is a post about the issue:
