if you compled alsa-driver in debug mode, you should see the following
message in system log.

realtek: Enable HP auto-muting on NID 0x1b
realtek: Enable Line-Out auto-muting on NID 0x17

The drawback is "Front Playback Volume" and "Front Playback Switch"
does not control the "Headphone Jack" which used as "Front" jack

The other method is using  "hp_pin" instead of "speaker_pin" to assign
"Front" dac 0x02

but this method won't create "headphone playback volume" and
"Headphone playback switch" since "hp_pin" is used to create "Front
Playback Volume" and "Front Playback Switch"
