<< Solved >> Catalina easy update and sound fix

[Bleysus]

Hello, all
Updated 2 machines from Mojave like real Mac (i3-5010/i5-5250, HD5500/HD6000)

1. Update Clover to Clover UEFI Boot Mode v2.4k r4961
info.plist from working Mojave - no changes
2. Download and install update from AppStore
3. All works fine except sound
Steps to fix sound (works on both machines):
1. Turn off sound hacks in Clover
2. Delete Voodoo from /Library/Extensions
3. Download latest AppleALC.kext and Lilu.kext and put them into /Library/Extensions
4. Search vanila AppleHDA.kext (I found from Mojave) if there is no such file and put into /Library/Extensions
5. The new files unable to work even after the kext rebuild because of the permissions, fix it

sudo chmod -R 755 /Library/Extensions
sudo chown -R root:wheel /Library/Extensions

6. kext cache rebuild

sudo kextcache -i /

Good luck )

Also, I've reformulated your solution a bit.

English is not my native language, so I write as I can ))

Uploaded files were downloaded from GitHub projects (AppleALC.kext, Lilu.kext)

AppleHDA.kext was taken from working Mojave.
In addition, maybe remount root partition is required, but that step do all, who uses hachintosh, after the installation, so I missed it.

sudo mount -uw /

4. Move Voodoo.kext from /Library/Extensions to another folder (as a back-up) if applicable

This is a third-party sound driver that do not work on Catalina, there is no sense to backup it.

Actually, it still works for some machines. My laptop works great with this (HP Probook G1). The speakers are weak and I set the boost level to 3 in the info.plist and I can hear the audio better than the stock settings.

Catalina has done some strange things with the Audio and some video ports on Hackintosh.
