Sorry, what do you mean? The facts I explored are:
- ad1884a_hp_automute() will be explicitly called by ad1884a_hp_init()
- ad1884a_hp_unsol_event() is never called on plug events
- I tried manually execute AC_VERB_SET_PIN_SENSE then read pin sense,
it takes effect on the impedance, but pin_presence still remains 1.

Not yet, will try it.

Yes. Note that the 6530s I have is a test box. Another 6531s which
is bought directly from market don't have this bug.

OK. Are there code examples for doing this? Thank you!
