Iceman Posted February 28, 2020 Share Posted February 28, 2020 (edited) Hi all,i have a Thinkpad Helix 2nd generation (Catalina 10.15.3) which it'is almost perfect working but the sound.It's a Broadwell platform, with Intel HD Graphics 5300 (working full QE/CI, by 191e8086/16260002, even on external display port). I was able to make it work with success even with the intel 7265 wifi experimental drivers. Even BT is successfully working!The only thing which is not working is the soundcard:8086:160C Name: Broadwell-U Audio Controllerit's a Realtek ALC286-VCThere is not any HDEF device, but i have HDAU (look at ioReg)... i tried to set alcid 3 and 11 through AppleALC (Vanilla AppleHDA), but nothing. I discovered (through Windows), the soundcard is an "I2C sound Realtek" (or i2s?)... but i am not able to convert it to HDA by DSDT/SSDT patches... (i'm supposing this could solve the problem...)Please help me find a solutionThank you CLOVER.zip Helix.ioreg.zip DSDT.aml Edited February 28, 2020 by Iceman Link to comment Share on other sites More sharing options...
