I'm not quite sure what you want to know but you don't need pin configurations, this is my code for alc888 on ga-p35-ds3l

Device (HDEF)
{
Name (_ADR, 0x001B0000)
Method (_PRW, 0, NotSerialized)
{
Return (Package (0x02)
{
0x0D,
0x05
})
}

OperationRegion (HDCS, PCI_Config, 0x54, 0x04)
Field (HDCS, DWordAcc, NoLock, Preserve)
{

PMES, 1
}

Method (_DSM, 4, NotSerialized)
{
Store (Package (0x08)
{
"subsystem-id",
Buffer (0x04)
{
0xA0, 0x00, 0x00, 0x00
},

"subsystem-vendor-id",
Buffer (0x04)
{
0x6B, 0x10, 0x10, 0x10
},

"layout-id",

}, Local0)
MCDP (Arg2, RefOf (Local0))
Return (Local0)
}
}
}
