Nailed it Mirone. MANY thanks Sir. Nigel

Mirone! This one works once you delete the GFXHDA file. Very well done! However, headphones sound over driven and distorted. Any suggestions? Almost there!

Do I need to reapply the patch via MaciASL or, seeing I'm using your original DSDT, I should just install this new Kext. If so, still not playing. Any specific files that would help debugging? Mo

Checked S/L/E. Only AppleHDA.Kext along with AppleGFXHDA.Kext L/E. Nothing HDA related and nothing Auto related in Clover Kext. Anything else I can send you to debug? Sorry about this. This is a tricky one. Mo

Hi Mirone. Used https://Olarila.com/forum/viewtopic.php?t=8238#p71316 to install the new Kext in S/L/E (after removing the old one). I also rebuilt permissions and cache using this app. Replaced the plist (thanks for some of the adjusts!) and the DSDT in patched. Rebooted...and...nope. I'll upload a new 'Send Me' and Clover folders (sep). I've removed some folders to save space on upload. Hope you have everything. Thanks for sticking with this one!

Morning Mirone. Thanks for your continuing efforts. Still no joy. To confirm. Your new AppleHDA.Kext has been installed in S/L/E and Cache rebuilt. The adjusted DSDT.AML (adjusted as I see for HDEF) is in the Clover Patched folder. Your new Clover config.plist (note the Kext patches) is being used to boot. Layout-Id in the config is not set I see (I presume this is correct). Send me debug file attached minus Kernel log and Clover folder in order to upload. This ALC on this laptop seems to be 'fun'! Mo Send me MacBook-Pro.lan 2 2.zip

Am I being an idiot Mirone? Replaced config.plist with your copy and also replaced AppleHDA.kext in S/L/E with your originally supplied Kext. Placed the AML file in the Patched folder in Clover EFI. Removed VoodooHDA.kext from Clover Kext folder. Rebuilt Kext Cache. Reboot. Boots, but no audio interfaces (other than my SoundFlower). I am right with the actions above? Please hit me if not! Thanks IOREG. Attached. Shows HDEF and reference to layout-id 3 Inc. ALC289. Mo ioreg.zip

Does this work for you? Note, I'm back to layout-id 2 in config.plist along with VoodooHDA (Yuck)...just to operate at present. AppleHDA is clean and original at the moment in /S/L/E The DSDT is a clean decompile from the AML extracted via Clover F4. No patching of any sort applied. Thanks Mo Archive.zip

Apologies for not replying sooner Mirone, especially after you have provided a patched HDA. I've replaced the AppleHDA with this one, adjusted layout-id to 3 however I'm struggling with the patching of the DSDT as the patch script will not apply...I presume because there's no HDEF in the DSDT. I currently have the HDAS renaming to HDEF in Clover ACPI patching. Any ideas? Big thanks for the support. Mo

Hia chaps. Give me an hour, I'll drop something in. Thanks Mo Added in 36 seconds: Didn't see it MaLd0n. I'll do a dump Added in 29 minutes 48 seconds: Hi Chaps. See attached. Linux Mint is seeing my card as an ALC289?! Defo a different ALC in the Dell manual...hmm. https://topics-cdn.dell.com/pdf/precision-15-7530-laptop_specifications_en-us.pdf Any suggestions? Thanks Mo codec_dump.txt

Hi. I've recently had success with a Precision 7530 laptop with an ALC3281. VoodooHDA is providing working audio via speakers but headphones are extremely distorted (over driven in my opinion). I've set layout 2 for my Mojave 14.3 setup. Any comments if your most excellent tooling will play nicely with the 3281? Thanks Mo
