The mute LED on the HP Pavilion Laptop 15-eg3xxx (PCI SSID 103c:8bfd, Realtek ALC287) does not work because the machine has no entry in the quirk table. No fixup is applied, so the mute LED is never driven, even though the mute function itself works. The LED is controlled via GPIO pin 4 (mask 0x10), which is exactly what ALC287_FIXUP_HP_GPIO_LED configures. This was verified on the hardware with hda-verb: setting the GPIO data bit lights the mute LED, and clearing it turns the LED off. hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x10 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIRECTION 0x10 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x10 # LED on hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00 # LED off Add a quirk entry for 103c:8bfd using ALC287_FIXUP_HP_GPIO_LED.
