Guys, need help with getting audio work on latest NUC10 Frost Canyon.

History - none of layouts under ALC256 folder of AppleALC did work, so we need a long way...

So far I was lucky to hear the sound with VoodooHDA.kext and AppleHDADisabler.kext, both from headphone jack and HDMI audio plus microphone works. At the same time there is an aim to get it working with AppleALC also.

What I've already done:
  1. There is a Voodoo_dump.txt output from getdump tool
  2. There is a Platforms.xml generated by GetDumpXML tool
  3. I prepared info.plist to inject to PinConfigs.kext
  4. I prepared layout12.xml for my config (used a sample file and changed CodecID as instructed)
  5. I added my Platforms and Layout to info.plist inside ALC256 folder
  6. Finally I even could build a new AppleALC.kext (enclosed) with the above Platforms.xml (renaming to Platforms12.xml) & layout12.xml
  7. Then I switched back to AppleALC
  8. MacOS starts and I see the needed sound input/output with alc-layout-id=0C000000 (alcid=12) injected, but there is no sound anywhere but MIC works

This is what I have with AppleALC.kext loaded.
