Title:
  [Latitude 3540, Realtek ALC283, Black Headphone Out, Left] No sound at
  all

Status in “alsa-driver” package in Ubuntu:
  New

Bug description:
  This bug manifested itself only recently (kernel update?).  I have
  sound through the internal speakers but nothing (except occasional
  clicks) through the headphones.  'What device did you plug in?' dialog
  appearing fine, headphones show up in sound preferences, test sounds
  not audible.
