spidey123 Posted May 30, 2020 Share Posted May 30, 2020 Hi guys, I just took the latest update for Catalina and lost my sound, which is normal until I reinstall my AppleHDA.kext, but even after re-installing my custom AppleHDA.kext (I have done this for the past two years) and installing the newest Lilu and Whatevergreen Kexts. I still cannot get sound. First time this has ever happened. Sound was perfect on Catalina 10.15.4 Did the update change the way sound kext work? Update. I reinstalled Vanilla AppleHDA 10.15.5 and added latest AppleALC to /EFi/Clover/Kexts/ and all is well again. I guess I missed that you didnt need a custom AppleHDA kext anymore. Probably been that way for a long time. Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 30, 2020 Moderators Share Posted May 30, 2020 What Codec does it have? ALC255? Can't you use AppleALC.kext with the corresponding layout-id? Post the kext you're using for Audio and layout-id used Quote Link to comment Share on other sites More sharing options...
arsradu Posted May 30, 2020 Share Posted May 30, 2020 @spidey123 It has. Patching the original AppleHDA kext is a pretty bad way to get sound working. :)) But it is/was commonly used on other forums for a while. So, I get where you're coming from. But also, as you noticed, you don't need that anymore. With this method (Lilu + AppleALC + layout-id), AppleHDA stays the same and the updates don't break sound anymore. Enjoy!

spidey123 Posted May 30, 2020 Author Share Posted May 30, 2020 Yes, you're correct. I hated always reinstalling the kext after each update. Much better like this. Thanks. Quote Link to comment Share on other sites More sharing options...
