E6230 Fine tuning Sierra (Audio+CPU+booting bug)

[misterju]

same thing  anyway is it much faster using the other option ?  

 

i attach the panic error in case it gives you more info

 

is there any other way to fix the sound ?

Replace AppleHDA to /S/L/E with this one. I think the one Hervé (278.52) included is newer than 10.12.1 (278.23)

Then run this 

sudo chmod -Rf 755 /S*/L*/E*

sudo chown -Rf 0:0 /S*/L*/E*
sudo touch -f /S*/L*/E*

sudo kextcache -Boot -U /

AppleHDA.kext.zip

weird it has same version as the one I had, anyway I did it with same results , still no audio and KP if I leave KernelBooter_kexts to NO,  if not maybe I can try generic voodoo drivers ? if so how ?

[Hervé]

If your KP refers to AppleIntelCPUPowerManagement, then you need to install the patched AIPCUPM kext in /S/L/E (overwriting the vanilla kext), repair permsissions and rebuild the cache. If you get an "error 77..." message, retype the touch + kextcache commands.

The kp Appears when I write no at kernels Playlist, yes avoided the error 77 but still no sound :/

[Hervé]

Again, what des the KP say???

 

You will get audio if:

1) you use the correct patched DSDT (HDEF layout-id set to 12 / 0x0C)

2) you install the IDT 92HD93 definition dummy kext, ideally in /L/E (/S/L/E will do to)

3) replace the vanilla AppleHDA in /S/L/E by the patched version (details of patch provided before) or configure the on-the-fly patches in Clover config.plist

 

Again, repair permissions and rebuild cache after any mod to kexts in /L/E or /S/L/E.

im not using the clover in this installation,  maybe in install it just to patch because i tried like 20 times the procedure and is not working on my case...   what patch should i need to apply  ? voodoo audio ?  thanks
