You need to issue get_pin_sense  after set_pin_sense of the same node to
get the impedance measurement of that node before you test another node

It is strange that your result is different from hdajacksensetest

If sound work with the previous version ,

Either 0x14, 0x15 and 0x16 are the headphone and speaker

So internal mic is 0x1a and mic jack is 0x18 if hda jack sense test report
present when you plug the mic jack
