About This File
According to @dgsga he changed the files ALC1150, he obtained audio to your ALC1220, starting from this principle, I did the same, I've modified my files ALC1150 and asked him to try for me and he gave me feedback positive.
he also confirmed to me that Asus uses a different id (0x10ec1168) while other manufacturers use (0x10ec1220), the same was confirmed by toleda here.
So Asus uses ALC S1220A and other manufacturers ALC1220.
it seems that now everything works well.
