I have alsa-utils and alsa-tools, but neither has hdajacksensetest
included in them. However I do have an output from HDA-analyzer :-

Title:
  [OptiPlex 9020, Realtek ALC280, Green Line Out, Rear] tinny sound

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  Sound equalization is normal when using jack in front of computer, but
  is "tinny" (i.e., low/nonexistent bass and midtones) when using rear
  output jack  with simple two channel headphones.

  Jack sense is working correctly because the internal speaker cuts out
  when a cable is plugged into the rear jack (or front jack, for that
  matter).

  Note Dell's website says this computer has a Realtek ALC3220, as
  opposed to the ALC280 which is detected by linux.  This is a clean
  install of 14.04, so I unfortunately I can't boot into Windows to
  observe its behavior.
