Awesome fix, Hui Wang, thank you! I'm on Lenovo ThinkPad X1 Carbon 6th, model 20KH006JGE. After upgrading to Linux 4.19.7, the audio mute and microphone mute LEDs (on F1 and F4 keys) stopped working. They do work if I remove the line:
{0x12, 0x90a60130}, Just removing it doesn't sound like the greatest idea, but I couldn't find the ALC285 datasheet online. If you could direct me to information about ALC285 registers so that I can fix the issue, or provide me with another value for the register so that I can test it, it will be greatly appreciated. Many thanks, Vadim. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1805079 Title: click/pop noise in the headphone on several lenovo laptops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1805079/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
