First all, since from Mountain Lion i have been patching AppleHDA in this computer (that uses ALC662 Rev1 codec - 0x10EC0662) without problems.
Until 10.9.1 i was injecting LayoutID = 12 in DSDT, then using my PathMaps (Platforms), my Layout12.xml and my corrected verbs (Info.plist), everything was fine.
With 10.9.2 release, i have patched the new AppleHDA as "normal" way. But it unexpectedly not worked. I have double checked everything...
I got an 'clean' AppleHDA and did all changes again, step by step.. Tried to change LayoutID to 1 (on both DSDT and files, of course).. Can't get it to work.
Tried to rollback to 2.5.3 version (working in 10.9.1), and for my surprise... Didn't worked.
I have only AppleACPIPlatform.kext (with vanilla i get stuck at boot) and AMDRadeonX3000.kext (for QE on ATI 5430 mobility) patched in my install. But these kexts have been patched since Mountain Lion.. So i guess that it's not causing this trouble.
Well, i have no idea what Apple changed in this release, that broken my sound.
Recently, i have updated to 10.9.3 to try with new kexts, but the version of AppleHDA is the same... Same results on tests.
Anyone has an idea?
Thanks in advance.
Ps: I have bin patched with bcc9 script (patch-hda - last version)
Ps2: In System Information and Sound settings i get NO DEVICES.
Ps3: HDEF infos are injected as well. (DSDT) - See IOREG attached.
