Hi Takashi,
I move check line to below. It will show value for hp_pins[0]. As I know, search from verb table in function snd_hda_parse_pin_defcfg(). It will fill pins at auto_pin_cfg. Why it need to run below function to get cfg->hp_pins?
It's just because hp_pins[] and speaker_pins[] are used for the case with the auto-mute, so far, not for other evaluations :)
The change below looks safe, so if this works for you, feel fee to apply like that.
thanks,
Takashi

Hi Takashi,
Chrome OS use early patch firmware file to load model and use auto_mute =no hint options. I find an issue for early patch issue about hint option auto_mute = no.
This will cause all spec->init_hook can't get hp_pin values.
For example: alc225_init() alc225_shutup() alc256_init() alc256_shutup() Early patch file hint auto_mute = no equal spec->suppress_auto_mute = 1 It will return function check_auto_mute_availability() in had_generic.c.
hp_pin = spec->gen.autocfg.hp_pins[0]; ==> It will get value 0.
I think this issue was for a long time. Please see the attach dmesg. One is kill hint auto_mute option.
