Simply replacing `.chain_id` with `ALC236_FIXUP_HP_MUTE_LED_MICMUTE_GPIO` directly inside `ALC236_FIXUP_HP_DM= IC` broke that existing downstream connection. To prevent any conflict and keep everything intact: We linked them sequentially so `ALC236_FIXUP_HP_DMIC` chains to `ALC236_FIXUP_HP_MUTE_LED_MICMUTE_GPIO`, which then preserves the rest of t= he downstream path (`ALC269_FIXUP_THINKPAD_ACPI`). This ensures: 1. The DMIC pin configuration (`0x12 -> 0x90a60160`) is retained. 2. The speaker mute COEF (index 0x20) and GPIO 0 mic-mute LED handlers are pulled in cleanly. Verification results on kernel 7.2.9: - `/sys/class/leds/hda::mute` and `hda::micmute` registered immediately und= er sysfs. - Native kernel triggers `[audio-mute]` and `[audio-micmute]` attached automatically without requiring any background scripts or hda-verb polling. - Both physical orange LEDs switch in real time with audio state toggles. - Digital mic array works properly via the AMD ACP6x driver. Subsystem ID `0x103c8dc9` is fully verified and ready for an upstream patch entry. --=20 You may reply to this email to add a comment.
