VT1708S Legacy kext and DSDT

That after injection device in many of my DSDT (ethernet, SATA, USB, sleep, shutdown, CG, SMBUS ...) I try desperately to inject my sound card is a VIA VT1708S in my DSDT.

For that I already know it takes a Legacy.kext but unfortunately I can not create it and I do not know how to inject my card in my DSDT ("Device (HDEF)" I guess?)

I have to retrieve this file on the net that are available hereCard_codec hex & dec ; PinConfigOverideVerbs and PinConfigverbsBIOS (send space.com/file/sqe48q)

Here I hope that someone will see this topic and how it will do and want to contribute finished DSDT!

PS

That is the moment I inject it in my DSDT:

Device (HDEF)
			{
				Name (_ADR, 0x001B0000)
				Method (_DSM, 4, NotSerialized)
				{
					Store (Package (0x0A)
						{
							"AAPL,slot-name", 
							Buffer (0x09)
							{
								"Built in"
							}, 

							"model", 
							Buffer (0x2D)
							{
								"Via VT1708S High Definition Audio Controller"
							}, 

							"device_type", 
							Buffer (0x06)
							{
								"Audio"
							}, 

							"layout-id", 
							Buffer (0x04)
							{
								0x0C, 0x00, 0x00, 0x00
							}, 

							"PinConfigurations", 
							Buffer (Zero) {}
						}, Local0)
					DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
					Return (Local0)
				}
			}

If something is more important to me personally I hesitate not do it anymore I try everything (although I have very little knowledge in the Legacy!

Without Legacy are my error messages:
