Quirk was applied in kernel 6.16:
https://github.com/torvalds/linux/commit/db98ee56851061082fecd7e6b4b6a93600562ec2
Unfortunately, it's not a "model" that can be applied by user at
runtime. Id you know how to alter pins and send verbs, maybe this will
help:
SND_HDA_PIN_QUIRK(0x10ec0294, 0x1043, "ASUS", ALC294_FIXUP_ASUS_HPE,
{0x17, 0x90170110},
{0x21, 0x04211020}
[ALC294_FIXUP_ASUS_HPE] = {
.type = HDA_FIXUP_VERBS,
.v.verbs = (const struct hda_verb[]) {
/* Set EAPD high */
{ 0x20, AC_VERB_SET_COEF_INDEX, 0x0f },
{ 0x20, AC_VERB_SET_PROC_COEF, 0x7774 },
{ }
