do you mean the commit does not fix the bug?
ALSA: hda - add support for Uniwill ECS M31EI notebook
the real cases are those desktop which does not use hda front audio panel ,
they just loss the auto mute since there is no jack detect circuit but they
can still hear sound from the headphone at anytime
do pulseaudio need a phantom port for the front panel headphone and mic
without jack detection ?
