Acer Aspire E5-471G Audio & Graphics Problem

Your patch for injecting layout-id is incorrect. It is referencing DTGP which is not defined anywhere. As a result, it will always fail.

...

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"

Determine layout-id from patched AppleHDA.kext:

First you need to know your codec id in decimal. Then look in the Info.plist for AppleHDAHardwareConfigDriver.kext (in PlugIns), find your codec id under HDAConfigDefault (there may be many entries in a sloppy patched AppleHDA or only one). The LayoutID that matches your codec id is the layout id you need.

I don't know where can I find my codec id...is it VendorID??
If yes, is it means the Info.plist for AppleHDAHardwareConfigDriver.kext haven't my codec id?
because I can't find it in there.

If your codec is Realtek ALC283, your screenshot shows the decimal codec id.

But I can't find my codec id in info.plist

But I can't my codec id in info.plist

With Clover, we usually use vanilla AppleHDA and an AppleHDA injector. You should not expect to find your codec in vanilla AppleHDA but instead look in the injector.

I can find my codec id on Info.plist in the realtekALC.kext and the LayoutID is 1, but still not working...

Desktop codec probably not the same as laptop. I have ALC283 on my u430... see here: https://github.com/RehabMan/Lenovo-U430-Touch-DSDT-Patch
