First, i found today that the "Master" Volume works with the speakers as
expected, and doesn't with the headphones like i said yesterday, when i
missed this detail.

Second, i found too other bug reports related to this, but that
bugzilla.kernel report it's very near, but i can't trust it because they
are talking about other specific notebook, and i don't know if that work
for me. But i will to read and test all info to apply and to find
solutions to my problem. And maybe, bugzilla kernel should be the site
for this report, or not?

Third, your solution with hdajackretask (with advanced override
activated), i don't have in jack any "HP" option, and there isn't any
0x1a connected. Green Line Out is 0x1b. Maybe i need to config to use
another AD1986A model (laptop-automute?) and not the default? Maybe PINs
0x1a (headphones) and 0x1b (speakers) are inverted and 0x1a jack
detection isn't detection properly (see hda-jack-sense-test above)?

I don't know it it's related: In hda_analyzer, 0x1a HP option is
enables, but in 0x1b HP option is disables, but both don't make any
differences.

At least the only thing i have to came now for the basic functionality
is the mixer for the headphones, because all the other changes in
hda_analyzer are working. I want to put the original text dump of
hda_analyzer in the affected pins, it could be useful:

PIN 0x1a (Change headphones) and PIN 0x1b (Change speakers) text dump from 
HDA_Analyzer when i made the changes to fix sound problems (except the 
not-working mixer for headphones)
