Second: Confirm your sound card layout-id: refer to:
https://github.com/acidanthera/AppleALC/wiki/Supported-codecs
Third:modify audio ssdt:For example:

This is audio's ssdt:

#include "include/IDT_76e0_HDAU.asl"
#define LAYOUTID 13
// inject properties for HDMI audio

{
If (!Arg2) { Return (Buffer() { 0x03 } ) }
Return(Package()
{
"layout-id", Buffer(4) { LAYOUTID, 0, 0, 0 },
"hda-gfx", Buffer() { "onboard-1" },
})
}
//EOF
modify
#define LAYOUTID 13
Change 13 to the ID of your layout id.
After modification, follow the steps of RehabMan: ./build.sh , ./install_acpi.sh xxxx
