I tried another fresh installation and update it (then it has kernel 3.13.0-43#72). Then I could not reproduce this bug.
I think I mess up something when trying to use bleeding edge alsa dkms to confirm this issue before updating kernel. Anyway it is ok now. ** Changed in: hwe-next Status: New => Invalid ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1407875 Title: [HP 14 Notebook PC][8086:1e20] mute LED does not work To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1407875/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
