--- Comment #17 from Raymond <superquad.vortex2 at gmail.com> ---
static const struct snd_kcontrol_new snd_ac97_ad1981x_jack_sense[] = {
    AC97_SINGLE("Headphone Jack Sense", AC97_AD_JACK_SPDIF, 11, 1, 0),
    AC97_SINGLE("Line Jack Sense", AC97_AD_JACK_SPDIF, 12, 1, 0),
};

these two controls only change JSMT2 and JSMT1


you need bit 2 and  bit3 of AC97_AD_JACK_SPDIF for JS0 ST and JS1 ST

create hp jack kctl similar to

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/oxygen?id=435feac648cab190990aa0bf9355f77d1f082db3

the point is when do the driver call snd_jack_report by interrupt or timer
