misc bit is set , this mean BIOS want to tell the driver that you front audio
panel does not support Jack detection,

driver won't enable unsolicited event for front panel headphone and mic

if your computer chassis have a hda front audio panel which support Jack
detection,  change the front audio panel type in BIOS setup or use early
patching to clear misc bit (bit 8 of pin default)
