I'm currently using AppleALC inside /EFI/Clover/Kexts.
Sound works fine through Laptop speakers. However, as soon as I connect my earphones, i start getting a continuous buzzing sound. Can anyone help me with this?
NOTICE: The official AppleALC now contains layout-id 72. There's no more need to download the AppleALC.kext.zip file from this post.
After several weeks of toiling (it's July already?!), here's a new audio solution for perfect working audio. I basically ported the linux driver and created a GUI popup menu to configure the combo jack (see screenshot).
Fully working Combo Jack! (Heaphones, headset, AND line-in!)
New verb sending kext (no more need for CodecCommander on systems without EAPD troubles; VerbStub is simply a direct port of hda-verb for Linux)
Launchdaemon with Windows-like pop-up menu monitors the jack for insertion
Automatic OMTP (Nokia)/CTIA (iPhone) detection for headsets!
Fully commented sources
Line-in mode disables audio output. I haven't been able to re-enable the speakers when the jack is purely an input, but that's the only "issue"
Zero "no audio after sleep" issues so far
Make sure to turn off "Use ambient noise reduction" when using an input that isn't the internal Mic (unless you find that it helps)
How does it work?
Simple! Due to the way the Realtek codec is set up on this machine, the ComboJack program watches the jack and switches the codec selector (node 0x22) to the correct input after applying all the requisite processing coefficients and pin widgets. This means that Mac OS only sees a built-in mic, but behind the scenes it actually is connecting to the headset and line-in ports. This works because all input paths lead through selector node 0x22 and into capture node 0x09, and the OS only acknowledges the capture node.
How to install (uses modded AppleALC):
Disable SIP (I use 0x67 for CSRActiveConfig and 0xEE for booterconfig) Remove ALCPlugFix from /usr/bin (may need to kill with Activity Monitor first) Remove good.win.ALCPlugFix.plist from /Library/LaunchAgents (may need to launchctl unload first) Remove CodecCommander from Clover/kexts/Other (unless you need it, but it looks like the 9560 doesn't) Copy VerbStub.kext to EFI/Clover/kexts/Other Copy AppleALC** to EFI/Clover/kexts/Other Change layout-id to 72 (in SSDT-Config -- 0x48 is hex) Run install.sh and read what it says Reboot (and enable SIP if you want)!
Download "ComboJack Installer.zip" and "AppleALC.kext.zip" for everything. The other zips are sources.
(Also included in "ComboJack Installer" is a folder containing the platform, layout, and pinconfigs used.)
**AppleALC now includes this layout (layout-id 72) in the official release.

Hi everyone !
I have a laptop thinkpad x1 yoga 2018 , the sound device is realtek alc285.
My friend and I spend numerous time on patching its layout-id , however either the headphone jack or laptop audio recording have noises.
Any help is appreciated , thank you !!!
I’m running macOS Catalina 10.15.2 on my Lenovo Ideapad 300-15isk laptop. Everything works, except HDMI audio. I can’t get it right no matter what I try, and I’ve tried every guide I’ve found. I was able to patch AppleHDA.kext and sound is working great, but still no HDMI audio in the sound properties window, only 'internal speaker out'. Here are my specs:
Lenovo Ideapad 300-15isk 80RS Intel core i5 6200U @ 2.40 GHz Intel HD 520 Graphics 16GB of DDR3L RAM @ 1600Mhz 480GB SSD as primary boot and system drive 1TB SATAIII HD as secondary. Backup drive Dual boot (macOS Catalina 10.15.2 and Windows 10 Pro)
Please refer to attached .docx file containing a picture of DPCIManager window and picture of Kexts installed in EFI-EFI-CLOVER-Kexts-Other. Also, in case you wish to look at it, I am posting the link to my RunMe files. Thanks a lot for your time and help!
