Hello, i'm trying to patch AppleHDA (OSX Lion 10.7.4) for Via VT1708S.
I've read some documents, and tryied the patch myself.

3 - I edited the AppleHDAHardwareConfigDriver.kext plist to match my CodecID and my ConfigData (verbs dumped from linux and parsed with verbit).
4 - I edited layout12.xml to match my codecID and to remove

MuteGPIO
5 - I rebooted, and my soundcard was detected :-), but i didn't patch Platforms.xml, and so no input/output devices :-(
The problem is that i don't know what to do exactely with Platforms.xml. I have codec graph and codec verbs, but i don't know where to put which node.
Could someone could please help me?
I attach here some dumped files
