Hi all:

Basically, ASUS CROSSHAIR VI HERO only provides Windows version, not
Linux version.

You can try it, after entering the LINUX OS (ALC1220, 0x10ec1022, subsytem ID: 
"sudo su root" type root password
"hda-verb /dev/snd/hwC1D0 0x20 SET_COEF_INDEX 0x15"
"hda-verb /dev/snd/hwC1D0 0x20 SET_PROC_COEF 0x06e0"
"hda-verb /dev/snd/hwC1D0 0x20 SET_COEF_INDEX 0x6f"
"hda-verb /dev/snd/hwC1D0 0x20 SET_PROC_COEF 0xc03b"
Try recording, will it still break?

If possible, please install the PATCH file in the LINUX Kernel source
and try it out.

Best regards

  Microphone distorted sound on ALC892/1220 on AMD chipsets

Status in Linux:
Status in linux package in Ubuntu:
  Won't Fix
Status in pulseaudio package in Ubuntu:
  Won't Fix

Bug description:
  Not sure if I'll report this upstream but there is definitely an issue
  with microphone recording on my desktop, this is not happening on my
  laptop which has a different codec.

  Already tried all workarounds possible, no luck. Only with my desktop
  with this particular motherboard. No issues in Windows, the sound
  recorded in there is distorted and has some static and robotic tone on
