Seems fine except the Audio Layout Injection.
The DSDT is still not patched fully.

I'm just trying to avoid mistakes of adding a wrong patch that's why i didn't patch anything else... Having seen my files, please which other patches am i missing?? I already did (battery, hpet, smbus, os check patch, rtc and brightness hotkey) And for audio, the layout-id 13 works it's just that sometimes if i boot especially from Windows 10 everything would be fine except that i loose the sound even though everything looks fine... I've seen others facing the same issues here --> https://github.com/acidanthera/bugtracker/issues/422 I don't just know what i need to do.

*update*
While googling my audio loss problem when booting from Windows, i saw another forum where someone with my codec reported the same problem. And the last meaningful reply i saw was that realtek in windows 10 was the cause. I can confirm it because on cold boot, audio works fine... I will ignore that for now and focus on my DSDT first.

Yes, some Audio Codec has this issue. Especially ALC295. Some sort of same issues in Razer Blade.

Yeah i did Continuous testing and the issue is only reproduced when i boot windows first then catalina. I did all the common patches following the guide in the first page

• HPET Fix
• IRQ Fix
• OS Check Fix
• RTC Fix
• SMBUS Fix

please what's left to be patched?

Well, i already mentioned what patches you need to apply but i'm mentioning it again.
For the DSDT

• Layout ID (whatever layout ID you're using in your config.plist for your Audio)
• Battery patch
• Rename GFX0 to IGPU
• Fix _WAK Arg0 v2
• Fix Mutex with non-zero SyncLevel
• HPET Fix
• IRQ Fix
• OS Check Fix
• RTC Fix
• SMBUS Fix

For all SSDT

• Rename GFX0 to IGPU
• Cleanup/Fix Errors (SSDT)

Repatch your DSDT with the above patches.

this patching was long longest patching I've done ... I've done it. I added sortorder. I will drop my acpi folder here ✌

*Edit* Here it is! if i need to upload any other file(s) i will do so!

I didnt include layout id in dsdt as my audio layout id (13) isn't available in rehabman's repo. Apart from that, i did evrything!!!

That's not an issue. Just change the layout ID. Change layout ID 12 to 13 in the patch. Here's the layout ID=13 patch for the DSDT.

#   Inject Audio info
into method label _DSM parent_label HDEF remove_entry;
into device label HDEF insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "layout-id", Buffer() { 13, 0x00, 0x00, 0x00 },\n
        "hda-gfx", Buffer() { "onboard-1" },\n
        "PinConfigurations", Buffer() { },\n
        //"MaximumBootBeepVolume", 77,\n
    })\n
}\n
end;

into method label _DSM parent_label HDAS remove_entry;
into device label HDAS insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "layout-id", Buffer() { 13, 0x00, 0x00, 0x00 },\n
        "hda-gfx", Buffer() { "onboard-1" },\n
        "PinConfigurations", Buffer() { },\n
        //"MaximumBootBeepVolume", 77,\n
    })\n
}\n
end;

Apply the above patch to your DSDT. Attach your files.
