it is suggested to use Xcode or PlistEditPro because clover configurator is known to corrupt/change/break Config.plist files,
Especially these recent versions:
i noticed that while generating a SMBIOS it enabled some DSDT Fixes on it’s own without touching that section;
In my case FixRegions.

Ohh sorry, I will replace Config.plist again with your one and when tested will upload all reports

I thought you were already using mine.

I was going to suggest you a clean install, good decision.

Just done new installation. After tested I see that Audio still doesn't work after wake from sleep

@Sniki, @RehabMan Any ideas?

PS: What is working after wake from sleep:
- internal microphone (Built-in)
-3.5mm jack( speaker and microphone)
Doesn't work:
-internal speakers-no sound

Hi Sniki, just to report that I unlocked my Bios and now replaced my Wifi card with DW1560, I have working Wifi and Bluetooth now!
Do you still would to help me with my issue no audio after wake from sleep? Also Wifi working very slowly after wake up( 28Mbps before and 2Mbps after wake up) Everything is like I use two different laptops

I would ask you as well how you fixed your new Wifi DW1560 to working with Windows? I tried lost a drivers, new clean installation Windows 10 but still don't have a Wifi signal(bluetooth is working fine)

Congrats,
Yes friend, i did finally fix Audio completely, also built a new Keyboard Map from scratch and now all Buttons work.
I will upload the x240 & L450 guide max till weekend and will add the improvements/fixes/changes.

You will have it all working after taking the files from the guide.

I will upload the audio files for you on the evening so u can test them.

About slow wifi after wake: just remove checkmark on “wake for network access” on SysPrefs>Energy Saver and issue solved.

My wifi and bluetooth worked fine,last time i installed for testing purpose was on the release of Creators Update and it worked fine.
Bluetooth and WiFi worked OOB with native Windows 10 drivers.
But i also found the driver from Dell support Site.
Just google for DW1560 drivers and im sure you will find them.
Like it’s obvious that Broadcomm didn’t build these cards for Hackintosh but they were used on Windows so you what i mean.

Also check if you somehow disabled Radio for WiFi,try with the keyboard shortcut Fn+F7 or the one that has wifi radio on/off.
Theres no reason for it to not work.
