You should search for an already patched AppleHDA for your codec.

Make sure you apply the required DSDT patches.

According to ioreg, no patched AppleHDA for your codec is installed.

I'm not sure layout=0 works...

into device label HDEF insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
Return (Package()\n
{\n
"layout-id", Buffer() { 0x01, 0x00, 0x00, 0x00 },\n
"hda-gfx", Buffer() { "onboard-1" },\n
"PinConfigurations", Buffer() { },\n
//"MaximumBootBeepVolume", 77,\n
})\n
}\n
end;

# IRQ fix
into device name_hid PNP0000 code_regex IRQNoFlags\s\(\)\n\s+\{(\d+)\} remove_matched;
into device name_hid PNP0100 code_regex IRQNoFlags\s\(\)\n\s+\{(\d+)\} remove_matched;
into device name_hid PNP0B00 code_regex IRQNoFlags\s\(\)\n\s+\{(\d+)\} remove_matched;

into device name_hid PNP0103 code_regex Name\s\(([^,]+),\sResourceTemplate\s\(\).*\n\s+\{((?:.|\n)*)\}\) replace_matched
begin
Name (%1, ResourceTemplate()\n
{\n
IRQNoFlags() { 0, 8, 11, 15 }\n
