mumsford Posted November 5, 2017 Share Posted November 5, 2017 Hello everybody, i recently managed to install high Sierra on my Lenovo Z70-80 CPU: I7 5500U GPU Intel HD 5500 / NVIDIA 840M (disabled) But i have no clue how to manage working audio. In Windows 10 the audio device is called "Conexant SmartAudio HD" that's it. I found several Conexant drivers, but they seem to be very specific like CX20XXX but i found nothing about the "SmartAudio HD" device. Link to comment Share on other sites More sharing options...

mumsford Posted November 6, 2017 Author Share Posted November 6, 2017 Thanks! I found several instructions but ... Copied the Lilu.kext and AppleALC.kext to EFI/CLOVER/kexts/other Also i put this patched DSDT.aml into the Patched Folder. Patched DSDT attached (and screenshot, showing no audio at all) DSDT.aml.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 6, 2017 Moderators Share Posted November 6, 2017 In Config plist, disable the AppleHDA patch under KextToPatch. Replace DSDT.aml with the attached DSDT.aml.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 6, 2017 Moderators Share Posted November 6, 2017 Ahh, forgot you're on High Sierra. Enable FixHeaders_20000000 in Config file under ACPI Link to comment Share on other sites More sharing options...
