This is version 2 of my patch. It implements suggestions from Takashi Iwai.
Thanks for that! Furthermore, I re-analyzed all the relevant coefs and
removed those that are not actually needed.
===
This patch addresses an issue where after rebooting from Windows into Linux
there would be no audio output.
It turns out that the Realtek Audio driver on Windows changes some coeffs
which are not being reset/reinitialized when rebooting the machine. As a
result, there is no audio output until these coeffs are being reset to
their initial state. This patch takes care of that by setting known-good
(initial) values to the coeffs.
The coeffs were collected via alsa-info, see:

working: https://pastebin.com/WUTufvZB
I also created a script which fixes the audio at runtime.
#!/bin/sh
hda-verb /dev/snd/hwC2D0 0x20 SET_COEF_INDEX 0x1a
hda-verb /dev/snd/hwC2D0 0x20 SET_PROC_COEF 0x01c1
hda-verb /dev/snd/hwC2D0 0x20 SET_COEF_INDEX 0x1b
hda-verb /dev/snd/hwC2D0 0x20 SET_PROC_COEF 0x0202
hda-verb /dev/snd/hwC2D0 0x20 SET_COEF_INDEX 0x43
hda-verb /dev/snd/hwC2D0 0x20 SET_PROC_COEF 0x3005
However, obviously, we can and should fix this in the kernel.
We initially relied upon alc1220_fixup_clevo_p950() to fix some pins in the
connection list. However, it also sets coef 0x7 which does not need to be
touched. Furthermore, to prevent mixing device-specific quirks I introduced
a new alc1220_fixup_gb_x570() which is heavily based on
alc1220_fixup_clevo_p950() but does not set coeff 0x7 and fixes the coeffs
that are actually needed instead.
This new alc1220_fixup_gb_x570() is believed to also work for other boards,
like the Gigabyte X570 Aorus Extreme and the newer Gigabyte Aorus X570S
Master. However, as there is no way for me to test these I initially only
enable this new behaviour for the mainboard I have which is the Gigabyte
X570(non-S) Aorus Master.
I tested this patch on the 5.15 branch as well as on master and it is
working well for me.

Thanks, applied now (with Cc-to-stable and Fixes tag).
