From: Christian Lachner <gladiac@xxxxxxxxx> commit c1933008679586b20437280463110c967d66f865 upstream. 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. 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.
