--- Comment #8 from Piyush (neonblade018@proton.me) ---
Hi Zhang,

I built and tested kernel 7.2.9 with those two chaining lines added to
ALC236_FIXUP_HP_DMIC:

    .chained = true,
    .chain_id = ALC236_FIXUP_HP_MUTE_LED_MICMUTE_GPIO

It works perfectly! 

Both LEDs registered under `/sys/class/leds/` as `hda::mute` and `hda::micmute`
with native kernel triggers `[audio-mute]` and `[audio-micmute]`. Both the
speaker mute LED and the mic-mute LED now toggle instantly in hardware on audio
state changes without needing any userland workarounds.

The internal digital microphone is also fully detected and functional via
ALSA/PipeWire.

You can consider this tested and verified working on my hardware. Thanks a lot
for the fix!
