[SOLVED] E6430: El Capitan 10.11.4 Missing Audio and getting KP with voodooPS2 kext

[jackchen858]

I am following this link: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide/

 

to install 10.11.4 on E6430, had same problem, no audio,KP unless CPUs=1. Tried the suggested VoodooPS2Controller.kext, didn't fix the problem. Finally tried ApplePS2Controller.kext, that fixed the problem.

 

 

 

 

I am still having audio problem. Copied AppleHDA_IDT.kext from the E6430.zip to /Library/Extensions, but it won't build:

 

bash-3.2# sudo kextcache -Boot -U /

rebuilding //System/Library/PrelinkedKernels/prelinkedkernel

IOKitWaitQuiet() timed out.

kextcache updated critical boot files, requesting launchd reboot

 

Maybe I had a wrong AppleHDA or AppleHDA_IDT?  I got AppleHDA_IDT from e6430.zip,  and there is a AppleHDA in /S/L/E:

 

ls -l /System/Library/Extensions/ | grep HDA

You need to keep the vanilla AppleHDA in /S/L/E

For 10.11.4, you need the updated AppleHDA_IDT in the Updated section in post #4

Thanks Crew. Yeah  AppleHDA in /S/L/E is untouched from installation, I believe it should be the original one.

 

When you say updated AppleHDA_IDT,  do you mean E6230_i5-3340M_HD4000_EC-Pack.zip   ? I am trying that one now.

Thanks so much, tried the one from the updated zip file, now I have audio
