you use need to set bit 8 of the pin default of the headphone to indicate that this pin complex has no jack detection circuit by early patching

the driver create front headphone phantom jack instead of front headphone jack
and won't enable unsolicited event to report the headphone state when the headphone is plugged/unplugged
The hd-audio driver reads the file via request_firmware(). Thus,
a patch file has to be located on the appropriate firmware path,
typically, /lib/firmware. For example, when you pass the option
`patch=hda-init.fw`, the file /lib/firmware/hda-init.fw must be
present.
The patch module option is specific to each card instance, and you
need to give one file name for each instance, separated by commas.
For example, if you have two cards, one for an on-board analog and one
for an HDMI video board, you may pass patch option like below:
------------------------------------------------------------------------
options snd-hda-intel patch=on-board-patch,hdmi-patch
------------------------------------------------------------------------
you should email the author since the source and ppa are already the latest version if you still got the bug
take a look at the early patching
