yves32 Posted December 15, 2015 Share Posted December 15, 2015 Thanks for clarifying. Strange you are missing that file, I have a fresh 10.11.1 build myself and not have that issue. I checked your config, you have ALC255, I'm sure this model uses ALC293. What audio kext are you using? Do you have HDMI video and audio working? I use VoodooHDA and HDMI audio does not work although HDMI video does. I'll test other kext and get ALC293 driver. Could you point me the direction?

Moderators Jake Lo Posted December 15, 2015 Moderators Share Posted December 15, 2015 Can you try my bootpack here? E5450_HD5500 That include the ALC293 kexts and patches for the Config file. Also included SSDT-1.aml for HDMI Audio. Let me know if the bootpack works for you. Link to comment Share on other sites More sharing options...

Thanks for putting together the bootpak. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 16, 2015 Moderators Share Posted December 16, 2015 Can you verify what sound card it has? Another member with the same system has ALC293 so I thought it would be the same on yours but perhaps it's not. Download DPCIManager, it should list what sound card you have or you could check the BIOS. Oh, make sure you remove VoodooHDA and AppleHDADisabler and restore the vanilla AppleHDA if you had removed it. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 16, 2015 Moderators Share Posted December 16, 2015 That's the same as ALC293. Check to make sure you don't have VoodooHDA and the disabler installed. Reboot without cache. Link to comment Share on other sites More sharing options...
yves32 Posted December 16, 2015 Share Posted December 16, 2015 I used your bootpack without voodooHDA. I saw AppleHDA.kext loaded from system report, and speaker and HDMI audio there. However, Audio preferences show no audio output/input device. ALC293 does not seem to be loaded. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 17, 2015 Moderators Share Posted December 17, 2015 either you skipped some output or none of the unsigned kexts are loading it should look similar to this rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext FakePCIID_BCM94352Z_as_BCM94360CS2.kext kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext FakePCIID.kext kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext EAPDFix.kext kext file:///Library/Extensions/DisableTurboBoostBattery.kext/ is in hash exception list, allowing to load kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext AppleHDA_ALC293C.kext kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext ACPIPoller.kext /System/Library/PrelinkedKernels/prelinkedkernel not cached.
