Title: [Lenovo T530]: Volume Mute key LED is not responding correctly Status in “linux” package in Ubuntu: Confirmed Status in “linux” source package in Precise: Confirmed Status in “linux” source package in Quantal: Confirmed Status in “linux” source package in Raring: Confirmed Bug description: Problem description: When attempting a hardware mute the volume mute action is applied correctly and the volume applet correctly displays that the audio output is muted. However, the mute key's LED backlight's responsiveness is flaky at best. Pressing the mute key repeatedly may or may not result in an mute key LED change. This can quickly get out of sync where it's possible for the mute key LED to be lit yet the volume is not actually muted. Again mute action does actually respond correctly via keypress: Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 87 Mono: Playback 63 [72%] [-18.00dB] [on] Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 87 Mono: Playback 63 [72%] [-18.00dB] [off] Software mute does not change status of LED.
