Hi Jake Lo, I had install Yosemite dual boot with Windows 10 (UEFI with GPT format) on Latitude E6230 and boot with Clover.
Spec:
Intel QM77
IDT 92HD93BXX @ Intel Panther Point PCH- High Definition Audio Controller [C-1]
Core i5 3220M
Intel HD Graphics 4000
I take bootpack, config.plist and dsdt from this thread https://osxlatitude.com/index.php?/topic/7478-dell-latitude-e6xxxe7xxx-yosemite-install-guide/
I also follow another thread and finally dual boot Yosemite and Windows 10 is working.
The sound can play before with Voodoo. But I wanna try to using AppleHDA, and found this thread. I install kext from here, my bootlag already kext-dev-mode=1, but still no luck.
How to fix this? Thanks before.
dsdt,ssdt,config attached.
