Diagnostic Summary: 1. Ruled out ALSA/HDA codec control: - The LEDs are electrically decoupled from the Realtek ALC236 codec. - Standard ALC236 quirks and direct hda-verb coefficient writes (node 0x= 20, verbs 0x500/0x400 on indices 0x0b, 0x19, 0x34) return value =3D 0x0 with no effect on the LEDs. 2. Input and ACPI Event Status: - Keypresses are properly received by the input subsystem (KEY_MUTE and KEY_MICMUTE). - acpi_listen shows that F5/F8 emit standard button events accompanied by WMI event notifications: button/mute MUTE 00000080 00000000 K wmi PNP0C14:01 00000080 00000000 button/micmute MICMUTE 00000080 00000000 K wmi PNP0C14:01 00000080 00000000 3. WMI & Driver Status: - Both the HP BIOS event GUID (5FB7F034-2C63-45E9-BE91-3D44E2C707E4) and command GUID (95F24279-4D7B-4334-9387-ACCDC67EF61C) exist under /sys/devices/platform/PNP0C14:01/wmi_bus/. - The hp-wmi driver instantiates the hotkey virtual input device, but do= es not register any LED class devices under /sys/class/leds/ for this board revision. Request: Please add support/quirk mapping for HP board ID 8DC9 (subsystem 103c:8dc9)= in hp-wmi to control the Embedded Controller mute and mic-mute LEDs. --=20 You may reply to this email to add a comment.
