I figured out what you meant. But AppleALC doesnt support amd and it didnt do a thing.
And sure voodooHDA does kinda work. Well "work" in the way that itll make your ears bleed and strain to hear anything because its so quiet and overshadowed by the high pitched ringing
for correct work you need to use VoodooHDA prefpane and edit Info.plist
ringing can be fixed by disabling input monitoring
quietness can be fixed by adjusting gain
I can't find VoodooHDA topic on this forum, only on russian applelife.ru
