ALSA: hda/realtek - Add support for ALC1220
Add Clevo-P51 mode support for ALC1220.
ALC1220 Clevo-p51
Speaker uses I2S output.
We therefore want to make sure 0x14 (Headphones) and 0x1b (Speakers)
use to stereo DAC 0x02.

Title:
[HDA-Intel - HDA Intel PCH, playback] No sound at all
Status in alsa-driver package in Ubuntu:
New
Bug description:
Hello to all,
My Ubuntu version is 18.04.02 LTS and I've setup a dual-boot with
windows 10. Speakers and audio jack work totally fine under Windows
10, but they never work with Ubuntu.
List of some of the things I've tried:
1) I've tried all the steps from the "Sound Troubleshooting Procedure"
2) I've tried installing the "oem-audio-hda-daily-dkms" package;
3) I've tried to install/remove/reinstall alsa-base, alsa-utils, pulseaudio,
pavucontrol many times
4) I've played with the options in the file /etc/modprobe.d/alsa-base.conf:
a) I've tried to add "options snd-hda-intel model=auto" and I also tried
different models: auto, clevo, laptop-eapd, clevo m-720, generic, basic and
even z71v position_fix=1.
5) I've tried adding :
Code:
[General]
description = Headphones + Digital Output (S/PDIF)
in the file "/usr/share/pulseaudio/alsa-mixer/paths/iec958-stereo-output.conf"
6) I've even tried a live USB stick with Ubuntu 19.04 (after reading
somewhere that this was fixed on 19.04), but I found out that there was no
sound on Ubuntu 19.04 as well.
