Trying again with my previous kernel since the new kernel seems broken

regarding loading the sound module

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
