MJKhaani Posted August 31, 2020 Share Posted August 31, 2020 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. Acer V3-571G Intel(R) Core(TM) i7-3632QM CPU @ 2.20GHz HDA ==> 10EC:0269 revision 1001 config.plist ioreg.iojones Link to comment Share on other sites More sharing options...

Andrey1970 Posted December 22, 2021 Share Posted December 22, 2021 If you use separate SSDT for HPET, then it is necessary to add ACPI Patch. Comment HPET _CRS to XCRS Base \_SB.PCI0.LPCB.HPET Find 5F435253 Replace 58435253 Link to comment Share on other sites More sharing options...
