sanghyun_lee Posted April 9, 2021 Share Posted April 9, 2021 My hardware Huananzhi X79 Big Sur E5-1650 v2 Radeon Vega 56 Audio : ALC887 Sympton HDMI audio is working I tried fixing audio from Mojave to Big Sur, but not worked. Well, I have HDEF device. But not working. I think that I tried almost of supported layout of AppleALC wiki. (sudo nvram -c is needed for each trial?) I uploaded my working efi folder except audio and removed intel wifi, bluetooth and resource folder due to big size of them. OC.zip For now, I can see HDEF device in IOregistry However not available in hackintool and DCPImanager only shows vendor and device ID.

Slice Posted April 9, 2021 Share Posted April 9, 2021 Do you want a sound or AppleALC? You may have sound with VoodooHDA. Sure it is very good sound on ALC887. 1 Quote Link to comment Share on other sites More sharing options...
