thx mald0n
So
my GTX is Ok right now
But about my ALC889 i used a voodooHDA.kext that i puted with kext utility
edit:
I tried: voodooHDA, Legacy889HDA, and ALC8xxHDA: nothing is ok
it appears on "about this mac" that the 889 is recognized but i don't have the optical ok!
ps: i tried to inject them with kext helper, kext utility and OSX86 tools
Ps2/ I think that if i use AppleHDA it will functiun BUT the pb is that i will have a kernel panic with voodooHDA on the boot, is it possible to delete voodooHDA and using AppleHDA???
do u have any suggestions?
many thx
edit2: after many tries, i have now the sound but not the optical output
if you have any ideas...
