According to your recommendations to repeat some commands

 

 

MacBook-Pro-Ami:~ ami$ sudo chmod -Rf 755 /L*/E*

Password:
MacBook-Pro-Ami:~ ami$ sudo chown -Rf 0:0 /L*/E*
MacBook-Pro-Ami:~ ami$ sudo touch -f /L*/E*
MacBook-Pro-Ami:~ ami$ sudo chmod -Rf 755 /S*/L*/E*
MacBook-Pro-Ami:~ ami$ sudo chown -Rf 0:0 /S*/L*/E*
MacBook-Pro-Ami:~ ami$ sudo touch -f /S*/L*/E*
MacBook-Pro-Ami:~ ami$ sudo kextcache -Boot -U /

 I've thought that something has gone wrong with the lspci I've installed before so I removed it to trash.

And made the commands again

 

MacBook-Pro-Ami:~ ami$ sudo chmod -Rf 755 /L*/E*

MacBook-Pro-Ami:~ ami$ sudo chown -Rf 0:0 /L*/E*
MacBook-Pro-Ami:~ ami$ sudo touch -f /S*/L*/E*
MacBook-Pro-Ami:~ ami$ sudo chmod -Rf 755 /L*/E*
MacBook-Pro-Ami:~ ami$ sudo chown -Rf 0:0 /L*/E*
MacBook-Pro-Ami:~ ami$ sudo touch -f /S*/L*/E*
MacBook-Pro-Ami:~ ami$ sudo kextcache -Boot -U /

MacBook-Pro-Ami:~ ami$ 

And again the status 77.

What is wrong with my actions?

Yes, I've rebooted but sound is missed. the icon is grey. Sorry(

I re-read your posts once more - not sure I understood everything right - in L/E/ I put AppleHDAIDT.kext and what shall I put in S/L/E/? Patched AppleHDA.kext?What does it mean patched AppleHDA.kext? If I'm right in S/L/E/ is already presented AppleHDA.kext so I should patch it? How can I do that?

No, just AppleHDA_IDT to /Library/Extension.

No patched kext necessary unless you're on Chameleon loader using Hervé's Chameleon bootpack.

The binary patch is done on Config.plist if you're on Clover using my bootpack.

Rerun these

      sudo chmod -Rf 755 /L*/E*

      sudo chown -Rf 0:0 /L*/E*
      sudo touch -f /L*/E*
      sudo kextcache -Boot -U /
 
If you get error 77, re run the last 2 commands, if you get 17, just reboot system.

Made all that you told step by step:

put the AppleHDA_IDT to /Library/Extension

​use config.plist from your bootpack (lores config; but i use only config; ssdt I generated from my config.plist - should I regain it from yours?).

rerun mentioned commands.

sound is still missed.

Put your dsdt - the screen devided onto 4 rectangles - sure this is some feature of dsdt. so I deleted it. and I made so minor changes in your config - change default boot volume and timeout. after that got reboot. first boot after those actions was corrupted - os version is not set yet or smth like that, but next reboot is ok.

sound is still missed(

 

 

 

Do you have DSDT patch for layout-id = 12 or 0x0C for hex

 

No, I don't even use dsdt. never had practice in patching dsdt. So the solution is that? How can I patch dsdt? and in case I use your dsdt is already patched? but what for screen artifacts (4 rectangles)
