Then why the "head" command returned void? :-?

Not yet :-)
But also run:
cat /proc/asound/card0/codec#* | grep Codec
Because you seem to have two different codecs listed.

Okay, okay... let's try then to restore the honour of your oldie laptop.

Mmm... that's the usual value for intel HDA chipset (the full list of
available modules are documented here):

(yours is and HDA ATI SB)

Wait. I must have missed this line from your very first post, but this
has to be your mic input (this is what I also get from my netbook and I
can from the mixer applet the "mic" is there) :-?
How are you testing your microphone?

Well, you can also try with a different one as this won't hurt:
options snd-hda-intel model=ref
And so on... (remember to reboot or restart alsa service after editing
the file to changes take effect)

Neither I do. That would be going very (very) backwards.

Yup.

Bored because of problems... never! That makes things even more
interesting :-)

Let's see if we can restore your recording capabilities.
