yves32 Posted December 17, 2015 Share Posted December 17, 2015 I move the 4 kext into /L/E and got error message. Then I removed them and use kext wizard to install them into /S/L/E. Rebuild cache and here is the output, same as yours: rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext EAPDFix.kext kext file:///System/Library/Extensions/DisableTurboBoostBattery.kext/ is in hash exception list, allowing to load kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext AppleHDA_ALC293.kext kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext ACPIPoller.kext kextcache updated critical boot files, requesting launchd reboot Reboot and speaker is working now. However, only speaker is available and no other devices such as HDMI audio, lineout.... Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 17, 2015 Moderators Share Posted December 17, 2015 HDMI audio only appears when you plug into an HDMI display that has audio output. Link to comment Share on other sites More sharing options...
yves32 Posted December 17, 2015 Share Posted December 17, 2015 HDMI audio does not show up when I plug into TV. Reboot with HDMI connected did not help either. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 17, 2015 Moderators Share Posted December 17, 2015 Does HDMI /Displayport Output show in 'about this mac'? Link to comment Share on other sites More sharing options...
yves32 Posted December 17, 2015 Share Posted December 17, 2015 No. When using voodooHDA.kext, HDMI audio was there although did not work. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 17, 2015 Moderators Share Posted December 17, 2015 Did you add the SSDT-1.aml to /EFI/Clover/ACPI/patched? Link to comment Share on other sites More sharing options...
yves32 Posted December 17, 2015 Share Posted December 17, 2015 Yes. I drop your entire folders, ACPI and kexts, into Clover folder to replace the old ones.. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 20, 2015 Moderators Share Posted December 20, 2015 everything looks fine with the reg. I even tested the config and DSDT/SSDT on my system with similar specs and HDMI Audio works just fine. Did you confirm your HDMI cable is working fine? Perhaps you might want to try different ig-platform-id Link to comment Share on other sites More sharing options...
