Trying to understand why installing kexts limited functionality

Adding to this thread as I'm trying to understand the when, where, why, and how Kexts and DSDT/SSDT.

I wasn't entirely sure where to begin: extracting, analyzing DSDT/SSDT, to start patching, or installing the Kexts that were recommended for my build (ThinkPad X1 Extreme). I opted for the latter just because it seemed "easier", didn't have that much time, and just wanted to see if it resolved the issues I made a checklist of.

The kexts recommended for my build:

X1E Hackintosh Kexts

Issues I'm having (which I'm not really asking for help yet to resolve, just providing context):

☐ Keyboard issues (mic mute and screen brightness don't work... audio, mute and volume control do work; CMD is ALT and not WIN key)

☐ Battery indicator (0% when unplugged)

☐ Fan noise (Mac Fan Control isn't detecting fan sensors to adjust)

☐ Thunderbolt devices (UAD Apollo Twin MKII audio interface) only recognized if turned on before macOS boots

These Kexts do reside in the /EFI of the SSD: this means they are automatically being loaded at boot correct?

That might explain somewhat the issue I was having after I installed each kext with (per RehabMan "How to install Kexts?"):

sudo cp -R KextToInstall.kext /Library/Extensions sudo kextcache -i / 

Then did a restart. Noticed that audio no longer worked at all, so I removed the ones I installed one at a time with:

sudo rm -Rf /Library/Extensions/KextToInstall.kext sudo kextcache -i / 

Restarted and audio was working again.

So at this point, I am back at Vanilla and with just what comes with the OS installed in /L/E.

So my questions at this point:

• Whatever is in /EFI/CLOVER/kexts/Other is being loaded automatically at boot?
• These should not be installed in /L/E too?
• If they are installed in both /L/E and /E/C/K/O, could it cause the weird behavior I experienced with audio no longer working?
• Furthermore, what should my approach be at this point in resolving these issues (with the help of Google): finding Kexts, using existing DSDT/SSDT patches, just Googling to find any type of solution, and/or patching my own DSDT/SSDT?
• Recommended resource should I use if I'm getting stuck interpreting and patching DSDT/SSDT (documentation, posting to forum [TonyMac, Reddit, etc...], etc...)?

By the way, some people on here seem to suggest installing all Kexts to /E/C/K/O and not in /L/E, but per RehabMan ("Installing Kexts"), I'm opting for /L/E/ and just leaving /E/C/K/O for what is "necessary to boot."

Anyway, diving into DSDT/SSDT tonight to try to wrap my brain around that. What little I've read, even as a developer (web), makes little sense to me when it comes to patching.
