0xffffffff = 0x80000000 + 0x7ffffff

Try the modified version of hda_jack_sense_test.py which need hda_analyzer
's codec parser and alsa python

https://bugzilla.kernel.org/show_bug.cgi?id=66621#c39

it need time for the impedance measurement to complete and become stable,
You may need to increase  time.sleep(0.02) if you still get 0xffffffff

https://bugzilla.kernel.org/show_bug.cgi?id=66621#c41

# the hda_codec.py file comes from Jaroslav Kysela's hda_analyzer program.
