[Fix] 10.11.4 broken audio with AppleHDA injector (dummyHDA)

[antonioj07]

Probook (hotpatch) specific instructions..

In Terminal:

# get copy of the repo
cd ~/Documents
git clone https://github.com/RehabMan/HP-ProBook-4x30s-DSDT-Patch.git probook.git

use it:

cd ~/Documents/probook.git
# update to latest (for future)
git pull
# install new AppleHDA_ProBook.kext
make install_hda

./download.sh and ./install_downloads.sh will also work to update/install all kexts (including AppleHDA_ProBook.kext).

I did this on my 4340s and now my boot is stuck on "Sound assertion AppleHDADriver line 3593" and line 1088

I boot fine from USB, and i´ve rerun PBI-CE but it does not fix the problem. I also can boot in safe mode

Boot verbose, show photo. Post EFI/Clover folder as ZIP (omit 'themes' folder).

You can follow the instructions in post #1, or switch to AppleHDA_ProBook.kext.

According to the information I have, 4x0s_g0 is IDT 76e0, which for AppleHDA_ProBook.kext is layout-id 17. To use AppleHDA_ProBook.kext, remove AppleHDAIDT.kext, change layout id in DSDT (from 12 to 17), and install AppleHDA_ProBook.kext.

Try boot without caches. Boot with your USB if needed.

Update Clover to the latest.
Update IntelBacklight.kext to the latest (see Projects link in signature).

Then rebuild cache:

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

Then boot normally.

Ok, i´ll do that. How about the correct procedure to fix my sound (4340s)?

Read post #1 to fix your AppleHDAIDT.kext, or switch to AppleHDA_ProBook.kext (4x40s uses IDT 76d9, therefore layout-id 13 in AppleHDA_ProBook.kext).
