Hi Toleda, mine is a particular situation: I use HDMI on a GTX260 over the internal SPDIF.
In the past, Intamara helped me to solve it on Lion (
http://www.tonymacx86.com/hdmi-audi...-edits-discrete-amd-nvidia-29.html#post292223). I tried to apply the same workaround on your new kext for Mountain Lion without success.
In attached my modified Platforms.xml (with Intamara advice), my DSDT and my codec dump.
Here the AppleHDA with Platforms.xml modified:

After Intamara help, I've studied to improve my knowledge. But maybe I failed
Please help me
For my ALC889 I have edited DSDT with this code:
Device (HDEF)
{
Name (_ADR, 0x001B0000)
Method (_PRW, 0, NotSerialized)
{
Return (Package (0x02)
{
0x0D,
0x05
})
}
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x04)
{
"layout-id",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00 /* Example, use table above for correct layout-id */
},
"PinConfigurations",
Buffer (Zero) {}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
}
and I have installed AppleHDA.kext inside the ML_AppleHDA-889-Alpha folder.
EDIT: It doesn't work also without my mod. No audio, also on analog stereo output.
