Title:
[Lenovo Y550P] Mute LED indication is inverted
Status in “linux” package in Ubuntu:
Confirmed
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).
