Hi there, my 1st post,
if possible I'd need some help to complete the patch I am trying to do on an AppleHDA.kext for my laptop (G74sx). It should have an ALC269VB, but i think it has a peculiar version of it, so standard kext patched don't work. I used and old version I found of AppleHDA.kext which worked fine till now (with some problems time by time), but is not working anymore in 10.9.2.
I followed all the 1st steps. I extracted codec_dump.txt, I converted to hexadecimals, I created the svg from these files, and so the verbs. I modified the info.plist from the 2 kexts inside the plugin folders.
My doubts start at this point.
1St of all, in the folder AppleHDA.kext/Contents/Resources, from an original AppleHDA.kext from 10.9.2, there are these folders:
English.lproj
Japanese.lproj
ko.lproj
zh_CN.lproj
zh_TW.lproj
And these files:
DefaultAudioLevels.plist
layout90.xml.zlib
layout92.xml.zlib
layout94.xml.zlib
layout120.xml.zlib
No trace of layout12.xml.zlib or platforms.xlm.zlib. But I see in other AppleHDA.kext already patched these files are present. So my 1st query is this: where are these files?
Anyway, I tryed to understand the structures of these files taken from other kext already patched.
It seems quite easy to modify the layout. But platforms.xml seems quite troubled to me. I don't understand enough the SVG file I created from codec dump. Especially, I don't understand these things:
the difference between dot lines and normal lines
the difference between grey and blue lines
which of the nodes I should check, considering that they seem to be more than I need
And I don't understand as well the structure that pathmap must follow. Without some suggestion it will take me a life to understand it properly.
I didn't try to patch the AppleHDA inside MacOS folder, but now I want to solve these other steps, if I find any problem at that point I'll post again.
I may need to review also my DSDT, but I think I can figure it out by myself. And if I won't, I'll ask.
I am open to any suggestion. I will attach the files I extracted so you can give it a look. Also, I'll add a converted version in PNG of the codec_dump_dec.txt.svg.
Thanks for any help
