Im not surprised, the laptop is 8 years old. But it still works

I'm not sure this is what you are asking for. Trying to draw it.
| *| <- internal mic (it's a hole)
| *| <- button for muting internal mic
internal speaker -> | * * | <- internal speaker
/ / <- jack 3.5 (headphone) black

There is also a s-video connector at the rear of the dock

I'm not comfortable with this. I've tried to do the best, but I must
admit that I don't understand really what it does.
But the fact is that after reading many docs and doing the following, it
- run hda-jack-retask, select "Headphone" for pin ID 0x14, then quit
- run alsamixer, choose via F6 "0 HDA Intel" card, unmute every control,
- run hda_analyser with the alsa-info output of the non working kernel,
and for NODE 0x14 PIN check "OUT" in widget control, and uncheck "IN"
After that headphone output and HP worked.
I know that saying this I'm not clear at all, but I don't understand
I hope this will "talk" more to you.
