Having a tool for reconfiguring the pins seems to be the only hope
for fixing the problems of all cards available out there.

However, I fixed my problem. The Dell Vostro 1400 (STAC9228) uses the model
"dell-bios" by default. The problem is that plugging the headphones does not
mute the speakers, and the digital mic does not work at all.

The model that works better is the "dell-3stack". But in this case there is
no analog mic available (the digital mic works, but it is too low).

Comparing the codecs I realizaded that the problem was that
the pin/node 0x0e (mic) was 0x01a19040 in the ref model and 0x01111212 in
the del-3stack. Then I just switched their positions in the initialization,
and voilá,
I have an analog mic using the model I want, that is, del-3stack.

Unfortunately, I know I did not contribute to anything. I just changed a
codec
to fit my needs, and maybe created a lot of noise tn the process.

Cheers,

and thanks for all the guidance I received.
