rubbereend Posted July 10, 2017 Share Posted July 10, 2017 Hi, Sierra runs pretty smooth on my Dell E5540, but the only problem I still have is the audio... I can't seem to find the correct kext for this model. According to the dell website the audio driver is a Realtek ALC3226. Does anyone have an idea? Thanks!

Moderators Jake Lo Posted July 10, 2017 Moderators Share Posted July 10, 2017 If you're using my bootpack and following my guide, it's all included. 7. Copy kexts from /EFI/Clover/Kexts/Other/LE to /Library/Extensions of Macintosh SSD Note: Ignore warning/error messages and click OK, then run commands below. 8. Repair permission and rebuild cache. Run command from terminal sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / Link to comment Share on other sites More sharing options...

Administrators Hervé Posted July 10, 2017 Administrators Share Posted July 10, 2017 ALC3226 = ALC292. AppleHDA patching details are available off my E6440 guide if you want. Link to comment Share on other sites More sharing options...
rubbereend Posted July 11, 2017 Author Share Posted July 11, 2017 Hello, I did a complete re-install of mac OS Sierra to be sure i followed the guide correctly, when i repair permissions and rebuild cache i get the following: rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext IOAHCISerialATAPI_Injector.kext kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext FakePCIID_Intel_HD_Graphics.kext kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext FakePCIID.kext kext file:///Library/Extensions/DisableTurboBoostBattery.kext/ is in hash exception list, allowing to load kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext CodecCommander.kext KernelCache ID: 7F8AC21A2AA4FC8829621EDE0CC18F27 File at path '/System/Library/PrelinkedKernels/prelinkedkernel' changed, cannot be used Child process /usr/sbin/kextcache[1207] exited with status 77. Error 107 rebuilding /System/Library/PrelinkedKernels/prelinkedkernel What am i doing wrong? Thanks, Roelof Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 11, 2017 Administrators Share Posted July 11, 2017 Nothing, you just have to repeat the touch + kextcache commands when you get that. But it seems you're missing the dummy ALC292 kext... It's available here in the bootpack and the ALC292 patch details are listed too. I'm using layout-id 1 on my E6440 (see post #7 of the thread). Audio kexts cannot be injected, they have to be cached if you want Clover on-the-fly patches to work Ok. Link to comment Share on other sites More sharing options...
rubbereend Posted July 11, 2017 Author Share Posted July 11, 2017 Hello, I've been trying again, this time with the alc 292 kext, now i don't get any errors after the sudo kextcache -boot -u / but still no audio output... I Don't understand what you mean with ' the ALC292 patch details are listed too. I'm using layout-id 1 on my E6440 (see post #7 of the thread). Audio kexts cannot be injected, they have to be cached if you want Clover on-the-fly patches to work Ok.' BTW: i've checked dcpi manager and for audio device i get 0x80869c20, if i google that i get the alc233 instead of the alc292. Am i using the correct kext? Thanks again!

rubbereend Posted July 11, 2017 Author Share Posted July 11, 2017 Hi guys, I managed to get audio up and running with the ' voodooHDA.pkg'. Everything works now! Thanks for your great help! Greetings, Roelof Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 12, 2017 Moderators Share Posted July 12, 2017 ALC292 is known to be causing static noise in the headphone, so VoodooHDA won't fix this issue. With the patch AppleHDA_ALC292 with combination of CodecCommander, that will be fixed. Also will enable HDMI audio if that's important to you.
