Hi everyone i have this laptop
2.39 GHz Intel Core i3
Intel HD Graphics 4000
4 GB 1600 MHz DDR3
Intel 7 Series
Ethernet AR8162
Wifi AR9565 (i know there is no way to make it work)

and according to the codec_dump.txt on linux
i have a Conexant CX20756
Vendor Id: 0x14f15114
Subsystem Id: 0x1179fa50
Revision Id: 0x100100

i tried a lot of methods to make the sound work, one with patched AppleHDA and also dsdt edit, but i think I'm doing something wrong is very late here so i better ask the experts thanks to anyone who can help, and also thanks to RehabMan to teach me before how to edit dsdt and ssdt. Thanks everybody.

Audio: Best result with patched AppleHDA. Google 'patch AppleHDA guide'. Search for suitable AppleHDA or patch it yourself. Apply appropriate DSDT patches.

DSDT patches you need for AppleHDA: https://github.com/RehabMan/Laptop-DSDT-Patch
Apply: "Audio Layout 12" (change layout-id from 12 to the layout-id used by the patched AppleHDA)
Apply: "IRQ Fix"

_DSM method is coded incorrectly (package length is incorrect).

Use instructions in post #2.
