[HELP][Acer V3-571g] No Audio Device No Codec ID

[MJKhaani 3]

Hi.

I recenty installed macOS Catalina on my acer v3-571g. Some years ago I'd installed ML & El with audio support through DSDT. Unfortunately my HDD died and I replaced it and never install macOS until now.

Now I using OC with Lilu, WhatEverGreen, AppleALC (Order Checked By the Way and All Kext Loaded - verified using kextstat) but no luck get HDA to work. tried all layout IDs  (specified in Docs for ALC269)  and even SSDT-HDEF injection, nothing work. I used -alcdbg -liludbg boot args and checked the log [log show --predicate 'process == "kernel" AND (eventMessage CONTAINS "AppleALC" OR eventMessage CONTAINS "Lilu")' --style syslog --source] and nothing in particular. I think something wrong with my ACPI because in DCPIManager I only saw one Audio Device with no CodecID or Revision.

 

If somebody help me to get to right direction I'll be thankful.

Add to HPET:

                       IRQNoFlags ()
                            {11}

 

And use layout 127

Thanks for answering but I already done that (I mean both layout & HPET).
