<< Solved >> ALC283 and thoughts about read-only

[razzvg]

Playing around with my old laptop and upgraded to Catalina quite smoothly, however I am not able to get ALC283 to work.

RehabMan stated the following here

ALC283 is the same as my Lenovo u430. You can use AppleHDA_ALC283.kext in my u430 repo...

https://github.com/RehabMan/Lenovo-U430-Touch-DSDT-Patch
get
Requirements:
- Clover bootloader
- config.plist must have the four AppleHDA patches from my config.plist in the repo (but not the zml.zlib patch)
- AppleHDA.kext must be vanilla
- CodecCommander.kext installed to /S/L/E: https://github.com/RehabMan/EAPD-Codec-Commander
- AppleHDA_ALC283.kext installed to /S/L/E
- rebuild cache following the procedure detailed in the u430 guide: http://www.tonymacx86.com/yosemite-...ideapad-u330-u430-u530-using-clover-uefi.html
- DSDT patches "IRQ Fix" and "Audio Layout 3".

The problem is, there is no write access to /S/L/E anymore. So my questions are:

- Is it really required for them to be in /S/L/E or can they be just patched via Clover?
- If otherwise should I disable SIP / use macOS root account in order to get it done. Or what will be the best practise on this?

*Also the problem reporting script does not work anymore because of this

best to just try lilu and AppleALC.kext installed /L/E and the appropriate layout-id in config.plist

Supported codecs

Native macOS HD audio for not officially supported codecs - acidanthera/AppleALC

Sadly I have done that already and the layout-id that worked fine on Mojave (id: 3) also shows up correctly in IOReg

are you using latest lilu and plugins? and using -lilubetaall boot argument?

Oh, I totally forgot about -lilubetaall. That did the trick for me! I guess it is soon time for a guide update

it's all about reading the available information

Hey all, had a similar issue using cx 8150 layout id 3. Where lilubetall and alc beta used to work in previous betas, my audio stopped working in beta 8. Any suggestions?
