Is alc_update_headset_mode() called when you plug/unplug the headphone
or the headset?  If yes, which value is set to new_headset_mode?

The same question applies.  This is a Dell machine with
ALC255_FIXUP_DELL1_MIC_NO_PRESENCE fix up.  The mic pin has no jack
detection but the detection is triggered only by the headset (HP)
pin.  All these imply likely that the detection of the headset mode
doesn't work properly.

I haven't touched with these Dell quirks, but Canonical guys did it.
They should have a better clue.  Now Cc'ed.
