  sound at all

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  Hello
  When I am plugging external headphones jack in the the headphone output of HP EliteBook 725G2, in the Sound Output window, device through which sound supposed to be playing, changing from "Speakers"to "Headphones". However, no sound is coming via headphones
  I tried with 3-pin headphones and 4-pin (the one that is with mic)
  Do I need to load some extra drivers in order that Ubuntu recognizes and plays the sound correctly via headphones?
  System info:
