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

There is a fix for this in the 4.19-rc tree right now. It's in Linus's
tree if you want to just use that repo, or just wait a few days and it
will be in the next 4.19.y release.
thanks,
