Title:
  [Acer Swift SF315-52, Realtek ALC256, Mic, Internal] Internal
  microphone not working

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  Recently bought a new Acer Swift 3 laptop and installed Ubuntu 18.04
  on it. Everything works except the internal microphone. I have also
  tested with an external microphone and this didn't work either.

  I have worked my way through all the suggested solutions I could find,
  including trying to reconfigure the pins using hdajacketask. In
  pavucontrol I have options for Internal Microphone and Microphone
  (unplugged) but the internal mic only captures static noise.

  The latest HD-Audio Codec-Specific Models has configurations for
  alc255-acer and alc256 for some other models, but setting options snd-
  hda-intel model=MODEL in /etc/modprobe.d/alsa-base.conf does not solve
  the issue with any of these.

  Some info -

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-
  LP HD Audio (rev 21)

  
  cat /proc/asound/cards:
