Title:
  Thinkpad SL510 Mute button not working

Status in “linux” package in Ubuntu:
  Won't Fix
Status in “linux” source package in Natty:
  Invalid
Status in “linux” source package in Precise:
  Won't Fix

Bug description:
  The mute button of my Thinkpad SL510 is no longer working in Maverick
  with Kernel 2.6.35.

  In Lucid it didn't produce an "XF86AudioMute" signal either but at
  least it muted the notebook's speakers (not the headphones) and
  illuminated it's led when pressed. Now with Maverick it doesn't work
  at all.

  Also the brightness controls don't work properly. Ubuntu's indicator OSD already is at it's left end when medium brightness is set. If i lower the brightness any further it starts over at it's right end. So from highest to lowest brightness, the OSD runs through twice.
