I have already tested it in the mainline kernel.  I ran the command as
told.  Same problem persists in all kernels I have tried.  Currently,
tested on uname -r = 5.3.0-28-generic the mainline kernel for 18.04.3
LTS.

Title:
  Gigabyte x570 Aorus Master with ALC1220 and ESS SABRE 9118 DAC Muted
  Front speakers 5.1

Status in alsa-driver package in Ubuntu:
  New
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 18.04.3 LTS
  Kernel 5.5.0
  pulseaudio:
    Installed: 1:11.1-1ubuntu7.4
  X570 Aorus Master Motherboard. ALC1220 ESS Sabre sound.

  I have surround 5.1 speakers and the Front Left and Right are Muted.  
  I have to unmute Headphones in alsamixer to hear sound from the front left 
and right speakers is the workaround.

  This step should not be required for speakers 5.1 to work.
