I have tried a few options but the only things that allow the UI to run
are the steps above.

For example If I revert the changes and run this commandline I get the
same errors.

sudo python hda_analyzer.py /proc/asound/card1/codec#0

Traceback (most recent call last):
  File "hda_analyzer.py", line 546, in <module>
    sys.exit(main(sys.argv))
  File "hda_analyzer.py", line 523, in main
    if read_nodes(sys.argv[1:]) == 0:

    read_nodes2(c.card, i)

    c = HDACodec(card, codec)

    self.wrongfile('unknown dig1 bit %s' % repr(b))

    raise ValueError, "wrong proc file format (%s)" % msg
ValueError: wrong proc file format (unknown dig1 bit 'KAE')


Apart from that the documentation on hda_analyzer is sparse and figuring
out what to do with the interface will require several hours of my life.

Maybe I have missed something with the alsa-jack-sense-test script or one
of the other python scripts but is it possible to script a tool that will
try out every solution and figure out which pins should be enabled or are
missing to achieve various results?
