791g

I have acer aspire v nitro 17 791g, I opened it up and I checked my motherboard, not sure if it's of any help, it says it is Posseideon mb 14203-1M 448 02G08, 001M and I have no idea which audio kexts to install, I have tried some with multibeast, but nothing worked, can somebody help me with this?
