MJKhaani Posted November 9, 2020 Share Posted November 9, 2020 (edited) Hi. I using Opencore with 10.15 & 11. I have to remove HDEF from DSDT to get the audio working (I tried to rename to something like FUHD but appleALC will detected it and and HDEF to device name). Can someone point me to correct path? I'll be grateful. Another problem (wrong forum I know) is brightness keys. I patched the DSDT and its working, then I wanna remove DSDT from Opencore and use hot patch or SSDT to get it working but no luck. I created SSDT for brightness keys (attached), I wanna know is it correct this way or have problem in SSDT? dstd-unpatched-linux.dsl ioreg.zip SSDT-BR.dsl Edited November 10, 2020 by MJKhaani Update1 Link to comment https://www.insanelymac.com/forum/topic/345653-acer-v3-571g-audio-other-dsdt-problems/ Share on other sites More sharing options...
