It seems that the mute LED could be controlled by ALSA instead.

Title:
  HP laptops: mute LED state is not synchronized correctly

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This problem applies to at least the HP 2230s and HP 6710b laptops, so
  the problem might be in the HP ACPI WMI driver or its integration with
  the rest of the operating system.

  Problem description:

  Ubuntu remembers what kind of volume setting and mute state I have
  when headphones are plugged in or not.

  The mute LED correctly changes on/off when the mute button is pressed.

  However the mute LED of the laptop is not updated to follow the actual
  remembered setting when headphones are plugged or unplugged.

  If the mute preference of the state of headphones being plugged in
  differs from the state of them being unplugged, this will lead to
  inverted behavior of the mute LED.
