I can confirm this on my Del  7537, I can't seem to find a solution. Did
anyone manage to do that?

Title:
  [Dell System Inspiron 15 7000 Series 7537, Realtek ALC3223, Speaker,
  Internal] Underruns, dropouts or crackling sound

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  The audio constantly clicks overtop of what is played. This began
  occurring after fixing a previous bug where audio would not play
  through speakers. All that was done fixing this bug was uninstall and
  reinstall pulseaudio and the alsa-base. Occasionally the clicks will
  be replaced by  random noise.
