Off-topic. As is clear in the title, this thread is not applicable to VoodooHDA.kext.

Hello,

I have updated to 10.11.4 and got like many others on my Lenovo Y580 the Sound Problem.
I have seen the Step by Step Post from 22 but under /System/Library/Extensions I only got the AppleHDA.kext and not the AppleHDAIDT.kext how its mention there. :-/

So can I also do it with this way with AppleHDA.kext?

Attach output of (in Terminal):

sudo touch /System/Library/Extensions && sudo kextcache -u /

Here the Output from the Terminal.

Here the Output from the Terminal.

Note:

kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext DummyHDA.kext

Terminal says: command not found

It is not a command for Terminal.

It is output you provided from kextcache. I asked for kextcache output because you were confused about how audio was implemented on your own computer.

It is clear from the output that you are using DummyHDA.kext and that DummyHDA.kext does not have the fix detailed in post #1.

Read post #1 to apply the edits to your DummyHDA.kext.

I read post 1 again and choosed to do exactly how Post #22 said.

And unfortunately the Sound does not work after a reboot.

See the Terminal Output from rebuilding cache. What is wrong please?

As is seen clearly from kextcache output, you did not fix DummyHDA.kext/Contents/Info.plist as per post #1.

Perhaps you should double check your work.

 

[Arsakuni]

I am sure I did how its said in Post #22

I have opened Info.plist in Contents folder with the text editor from El Capitan.
And add the code under <key>OSBundleLibraries</key> <dict>

Than I saved it and used KextBeast on the desktop, they were only 1 to choose from 2 so I`ve choose
/System/Library/Extensions and it was successful.

And I booted without chache from clover boot menu, the rest you know from my output.

Edit: Can me please someone help me with my Problem, because I think I did exactly how the Post #22 said. Only in my /System/Library/Extensions its called AppleHDA.kext and not AppleHDAIDT.kext
is this maybe the Problem?

Also I want to mention that I use Lenovo Y580 Notebook and not ProBook 6570b
