RoberT_XeS Posted January 26, 2022 Share Posted January 26, 2022 (edited) NEW METHOD: SSDT Patching Method 1. Add all the following "TMR IRQ 0 Fix": <22010079 00> -> <22000079 00> "PIC IRQ 2 Fix": <22040079 00> -> <22000079 00> "RTC0 IRQ 8 Fix": <22000179 00> -> <22000079 00> (Note: These values might be different for you depending on the IRQ Hot patching required for your System. Some may even need IRQ 15 Fix. You can try these values as well. For detailed explanation scroll below in the comment section and read the explanation from @Bill Huang) 2. Also add the SSDT-HDEF-edited.aml in to the ACPI folder (Note: You need to edit this SSDT-HDEF according to the path of your audio location . My audio location was under Scope (\_SB.PCI0) Your audio HDEF location might be different you need to edit the SSDT accordingly. You can use Hackintool and under PCie Section you can find your Audio Location) 3. As you can see I have added the location according to the location I found in Hackintool. i.e \_SB.PCI0 in the SSDT-HDEF-edited.aml file 4. Add the SSDT-HDEF-edited entry into the config.plist as shown below 4. Create SSDT-HPET.aml using SSDTTime from Windows or Mac and add it to ACPI Folder. 5. Also add the entry into config.plist as shown above 6. Add the patch in to the config ACPI>Patch section that SSDTTime app gives you named patches_OC.plist 7. After adding all the above reboot the system and your Audio should start working. If the above method does not work for you then you can follow the below given guide. OLD METHOD BUT STILL EFFECTIVE AND WORKING DSDT Patching Method: Most of might be able to get the audio working using the Dortania Guide but many are unable to get their ALC Audio working with that guide in BigSur and Monterey. Like you I also tried many solutions but none worked. I have ALC 892 and it worked after DSDT Patching. This patch works for other ALC Audio as well. This guide is only for those who has exhausted all their options and don't know how to get the Audio working. I will try to make this guide as simple as possible. Just follow all the steps mentioned below and you should get your Audio Working. Do not skip any of the steps. Use only Rehabman's MaciASL. Method: First of all you need to check if you have the latest AppleALC.kext and Lilu.kext are present in EFI/OC/Kexts. If not then download and paste it inside the Kexts folder and then continue with the guide. Second of all I assume that you have exhausted all the options to get your audio working but still no Audio then the guide is for you. 1. Download the last Rehabman's MaciASL and then open it in Mac. You will see the following. If you see the following then your DSDT is already loaded. If it is not loaded then you need to use other methods to get your DSDT and open it in Rehabman's MaciASL. 2. Now click on MaciASL Menu and then go to Preferences and then click on Sources and add the following and close the dialog. Toleda HDMI http://raw.githubusercontent.com/toleda/audio_hdmi_uefi/master Toleda HDMI 8 http://raw.githubusercontent.com/toleda/audio_hdmi_8series/master Toleda ALC http://raw.githubusercontent.com/toleda/audio_ALCInjection/master _RehabMan Laptop http://raw.github.com/RehabMan/Laptop-DSDT-Patch/master 3. Now click on the Patch icon and select 'Add dsdt/HDEF/Audio ID:1' and click on Apply (Note: If Audio ID:1 do not work for you then you can try the other patches in the list) 4. Now Select IRQ Fix under Rehabman's Laptop Patches and then press Apply. (Some should have their audio working with the above audio patch but for the rest you need to apply the IRQ Fix as well.) 5. . Now press the Compile Button and check if you are getting any error like this. If you are getting error then close everything and repeat the steps 1 to 4 again. As you can see I am getting 0 Errors. 6. Save the file as ONLY_AUDIO using the ACPI Machine Learning File Format. 7. Now mount your EFI Partition and then place ONLY_AUDIO.aml in the ACPI Folder under EFI/OC/ACPI/ 8. Add the ACPI entry in config.plist using Propertree or PlistEditor or OpencoreConfigurator. I am using Plist Editor. 9. Add Boot Args: alcid=1 (Note: This value depends on your Supported Audio Layout. You can check your supported Audio Layout here https://github.com/acidanthera/applealc/wiki/supported-codecs ). Mine works with Layout ID 1 hence I am using alcid=1 in this guide. The layout ID may be different for you. 10. Save the config and then reboot and now you should have your Audio Working.

RoberT_XeS Posted January 27, 2022 Author Share Posted January 27, 2022 (edited) 13 hours ago, Hervé said: This is all fine but kinda deprecated with the demise of DSDT patching in favour of using patched SSDTs as alternatives. These do include dedicated SSDTs for patching HDEF device and/or HPET device for IRQ. See the Dortania documentation on the matter for instance. I tried all that but was unable to get it working... I tried SSDT-HPET, and SSDT-HDEF with IRQ fix but none worked. This was the only way for me to get ALC 892 Working. If you can provide an alternate SSDT-HDEF and IRQ Fix then I can try. One of my friend has Sabertooth X79 and he just have to add alcid=1 and it works. But I have Huananzhi Chinese Motherboard same ALC 892 and same Audio Layout but it do not work it needs DSDT Patch Edited January 27, 2022 by RoberT_XeS Link to comment Share on other sites More sharing options...
RoberT_XeS Posted January 28, 2022 Author Share Posted January 28, 2022 (edited) 16 hours ago, Hervé said: To patch HPET, one needs to: 1) rename the original ACPI device to XPET (or whatever other name) 2) inject the replacing code (with IRQ patch) through a dedicated SSDT 1st action is required or the patch will simply be ignored because one cannot redefine an existing device, only add new properties to it. By renaming the original device, one basically opens the path to create a new one that will entirely replace the original one. This is pretty well documented in the Dortania documentation. Look it up. I used SSDTTime to get that SSDT-HPET Patch. Even then it didn't work Edited January 29, 2022 by RoberT_XeS Link to comment Share on other sites More sharing options...
BillDH2k Posted February 25, 2022 Share Posted February 25, 2022 (edited) You will need to hot-patching the IRQ's (0, 8, 11, may be 15 too) to make Apple ALC work. Your DSDT patch did that for you. For SSDT only method, you will need to add IRQ patching in your config.plist section: Root->ACPI->Patch (see below) The following is an example I did for my HP Z820 (also applies for Z420/Z620), for fixing IRQ 0, 2, 8, for Realtec ALC262 to work under Apple ALC. You could easily figure out the signature string for fixing IRQ11 (may be 15 too), by examining your original DSDT code. Good luck!

I did not emphasize that since I was assuming you are doing that. These IRQ hot-patching's and the SSDT-HDEF were the additional fixes needed. They were in your DSDT patch but missing when you transition to SSDT only solution. Glad it worked out for you! This approach can be used to fix most audio issues, if you have a working DSDT patch (such as the DSDT patch you suggested in your original post). Also, to figure out what IRQ's need to be patched, you can compare the original DSDT with the patched working DSDT, to see what IRQ's were zapped when the Rahabman's fixes were applied. Just Search "IRQ" string with maciASL, one can easily figure that out. In your case, as well as mine, IRQ 0, 2 and 8 were the ones.
