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:
