Anatoly Trosinenko, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.17 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-1ecn33ww ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - [Lenovo Y550P] Mute LED indication is inverted + [Lenovo IdeaPad Y550P] Mute LED indication is inverted -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1380249 Title: [Lenovo IdeaPad Y550P] Mute LED indication is inverted Status in “linux” package in Ubuntu: Incomplete Bug description: Steps to reproduce (on my hardware): Boot Ubuntu 14.10. Press "Mute" hardware button several times. What is expected: When mute is on button LED is on, when mute is off button LED is off. What really happens: Mute button LED state is inverted relatively to what is expected. Notes: This bug is reproducible also when booted into the root shell of the recovery mode and switching mute state on/off with alsamixer while playing some audio file to control the actual mute state (button press does not mute/unmute sound in this case, but LED switches on/off in respond to alsamixer).
