Hi,
I'm not sure what the connection is exactly but commit dcd51305cd41
("ALSA: hda/realtek - fix the pop noise on headphone for lenovo
laptops") broke the mute button LED on my Lenovo X1 Extreme laptop.I don't have any more info frankly and don't even know where to start debugging. Other LEDs work fine. This mute button LED never had any entry in /sys/class/leds, I'm not sure how it's handled. Let me know if you need more debugging on my part. Best regards, Bartosz Golaszewski
