"hdajacksensetest -a" gives
Pin 0x05 ( Digital Out, HDMI): present = No Pin 0x06 ( Digital Out, HDMI): present = No Pin 0x07 (Not connected): present = No
which is a bit of a surprise to me, since at least the headphones (of the
headset I plugin) has working jack detection. I would expect to see at least to have 1 non-HDMI pin connected.
You need to specify card number
hdajacksensetest -c1 -a
If the external subwoofer can be detected with other unconnected pin complex instead of node 0x1a jack sense, you need to call snd_hda_jack_add_kctl in your fixup
snd_hda_jack_add_kctl(struct hda_codec *codec, hda_nid_t nid, const char *name)
Can user giveup some combo jack capability (remove the support of
headphone and mic jack and only support headset ) by early patching to reenable auto mic selection ?
To this I don't know the answer.
An image of the side with the different jacks:

The yellow is the external speaker The one next to the USB ports is the headset with a logo of a headset and
a microphone drawn in it.

No need to change if you are using headphone since default is headphone
Support of Headphone mic can be removed by alc_fixup_headset_mode_no_hp_mic()
You need to hack the driver to set current_headset_type to cita or omtp instead of unknown
spec->current_headset_type = ALC_HEADSET_MODE_UNKNOWN;
