Yes, Speakers <=> Headphones, and Mic are working. I have attached my rebuilt AppleALC and a txt file with the steps I did. Archiv.zip

Hi, I am having issues with ALC299 (ALC3271) on Dell XPS 9370 on 10.14.4. As non of the provided layout-ids had been working for me, I had rebuild AppleALC. With one the Speakers and Mic are working. Also Headphone detection is working, but no sound. The other one gives me working Speakers. Mic and Headphone are detected but non of them is working. I tried to send verbs with had-verb to fix the combo jack without success. I would appreciate any help you guys can give, thanks in advance! UPDATE 3.5.: All PinConfigurator Apps did not work for me, so I patched it manually. Changed layout and platform xmls. Everything is working now. Speaker, Mic, HP. ;-)))))))))))))) troubleshooting.zip

Hi hexdump, unfortunately sleep functionality is not working proper on my x201. It falls to sleep but it never gets back. I have to reboot the machine. Hotkeys for brightness are working fine. Temperature sensor indicates most of the time between 48 and 60 and the fan is always running at half turn. Sry that I can not provide you a full working DSDT.

Reaching the installer and installing went quiet smooth. I only placed the DSDT into EFI/CLOVER/ACPI/patched and edited the config.plist after the post installation. Under ACPI I ticked "Generates PStates" and "Generate CStates" like I did in my previous installation. Working: Sound -> VoodooHDA Trackpad -> VoodooPS2Controller Battery Indicator -> ACPIBatteryManager LAN & WLAN -> IntelMausiEthernet and replaced WIFI card QE/CI -> AppleIntelHDGraphicsFB (Guide) Is it possible to patch the gfx on the fly with clover like it did in the installation guide for Yosemite, page 5?

I will do so in the next days. As i read that you wrote sleep functionality is not working currently in HS I tried Sierra. Audio works fine in Sierra. But sleep does not. When I push the Mac to sleep it sleeps for 1-2 sec and then get back.

Hi EMlyDinEsH, i´m not a newbie in patching AppleHDA as i successfully patched my CX20585. But now i have a HP G72 from my working colleague here and i try to patch the ALC270, because all the kexts floating around do not work for me. I have tried layout 12 and 28. Only headphone is working with the patched kext. With voodooHDA i get full sound. Inject via clover, no DSDT injection. Please can you take a look or do you have some ideas? Thank you Mod_28.zip Patched_AppleHDA.rtf

With your method you have an unsigned kext installed. kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext AppleIntelHDGraphicsFB.kext You have to know which LW (Link Width) you are using, otherwise no chance for clover to patch this. For more information read #1 and #1141. There are no patched kext in the QECI folder; it includes the original FB. You can download unsigned, patched kext here.

This may be a little bit off topic.... When i change the volume within the slider in the menu bar, it changes simultaneously in system preferences section sound. But if i change the volume within system preferences slider and thereafter look at the slider in the menu bar it hasn´t change the value. Also i notice that after startup the volume for the internal speaker is always set at highest level, regardless of the value before. When the headphone is pluged in, any volume changes are remembered after reboot. Any suggestion about this?

This is such an awesome guide! I found several Conexant CX20585 kext, but neither worked for me to get internal mic working too. A big handshake to EmLyDinESH! Thank you so much for sharing your experience with us.

Note: Clover Configurator will convert the values to HEX, so we have to add the patch manually and place it inside the "KextToPatch Array".

Are you able to share your EFI right now? I have also tried to install yosemite. By default i could not reach the installer. So i changed AppleIntelHDGraphics*.kext as mentioned, Within this method i can reach the installer. After installing Yosemite i rebooted the system and choosed the new Yosemite installation to continue Apple´s post installation. It did some work and then unfortunately it stucks, it can not reach the desktop. I think this a problem with the framebuffer. The screen is grey with stripes,... What can i do? It is not clear for me, because patched *.kexts worked out well to reach the installer and after reboot it stucks. Are the kext gonna override after installation? Additional work: I just booted into an running OS X and removed NV*.kext, AMD*.kext, Geforce*.kext from Yosemite HDD, ATI*.kext, and AppleIntelHD*.kext, and applied patched AppleIntelHD*.kext to the /S/L/E. Just booted the Yosemite installation and now ended up [iOBluetoothHCIController][start] -- completed
