--- Comment #12 from Piyush (neonblade018@proton.me) ---
Hi Zhang,

I am currently tied up with other work and cannot do a clean kernel recompile
right now, but from the hardware routing logs:

The internal digital microphone on this AMD platform is handled by the AMD ACP
SoC driver (`snd-soc-acp6x-mach`), appearing as a separate hardware device
entirely from the Realtek codec. 

Bug 221233's assumption about pin 0x12 was likely a misdiagnosis because on AMD
Mendocino/ACP6x, the DMIC data lines do not pass through the ALC236 pins.
Therefore, mapping `0x103c8dc9` directly to
`ALC236_FIXUP_HP_MUTE_LED_MICMUTE_GPIO` should be all this machine requires for
LED control.

If you submit that patch to the tree, I will be glad to do a final confirmation
boot whenever I have some free time.
