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


https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa/HD-Audio.txt

Node 0x1b [Pin Complex] wcaps 0x40058f: Stereo Amp-In Amp-Out
  Pincap 0x0001373e: IN OUT HP EAPD Detect Trigger
    Vref caps: HIZ 50 GRD 80 100
  EAPD 0x2: EAPD
  Pin Default 0x02214c20: [Jack] HP Out at Ext Front
    Conn = 1/8, Color = Green
    DefAssociation = 0x2, Sequence = 0x0

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

[pincfg]
0x1b 0x2214d20


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
------------------------------------------------------------------------
