Title:
  [HDA-Intel - HDA Intel PCH, playback] No sound at all; sound works
  when I turn on the computer and login after the computer is off, but
  if i close the lid computer suspends, and upon wakeup from suspend no
  sound from built in speakers and built in microphone also does not
  work.  If shut down and restart then both internal speakers and
  microphone will work.  I have tried all available settings to fix
  this, but as a regular user, I have not been able to fix problem.
  Thank you for your help.
