Hi pro,

Recently, I've patched codec ALC 272X for my friend's Acer laptop. It's odd that the kext only works after sleep and all input and output devices are detected but no sound at all. I think this is because of sth related to EAPD but I don't know exactly what to fix. I attach here the codecdump along with the kext I patched. I would appreciate it if someone could help me with this problem.

Thank you so much!
