    Did you get a sound from the rear jack? 

  This mac mini has two rear analog jacks, one marked as input, one marked
as output "headphones". I currently have outputs plugged into both
ports, but I have yet to get any sound from either one.

This is exactly how it looks:

Ah-ha just what I thought chipset 82801G :)  Known to be badly wired by
hardware manufacturers. On the macmini the linux kernel used to send
the output to the line in so plug into that :) 

cat /proc/asound/card0/codec#* | grep Codec 

Let's asume that you get STAC9220/9221

And since this white little box contains the Atheros
Communications, Inc. AR242x 802.11abg Wireless PCI Express Adapter
it's an 2006 macmini which means version 1 or 2 I think first try it
with the /etc/modprobe.d/alsa-base.conf  ( if none then none ) and make
sure nothing is blocking line in since the audio might be passed out
that way ;)  alsamixer -c0 and to monitor pulseaudio output kill
pulseaudio ( pulseaudio -k ) and start it verbosly ( pulseaudio -vvvvv 
) If nothing ( without out any extra alsa tweaking put options
snd-hda-intel model=intel-mac-v1 ( or 2 or auto )
/etc/modprobe.d/alsa-base.conf and repeat :)
