Hi Mirone, i've followed the above guide and finished in creating an applehda for my asus s400ca which has a alc269 codec. Im doing this as i tried all of your kexts and it doesn't work as some are either internal speakers works the rest doesn't or the whole thing just doesn't work at all. But my patched applehda doesn't work too. I need your help. Can you help me check what i have done wrongly?? Also, i copied all my modified verbs i get from the verbit.txt to pinconfigurator and parsed the data but only 3 out of the 5 appears. Why does that so? Im pretty sure i did something wrong as there are some parts i don't understand really well. I need you and ideepak to help. Thank you very much. Really sorry to bother you guys. Below i've attached the my kext, codec dump that i got from linux, verbit and verbitdebug, codec_dump.svg in the codecgraph folder. Thank you very much.
