audio seems ok using layout 11, and headphones works fine as well, it is just the issue after waking from sleep then headphone audio is distorted, hence the need for CodecCommander.kext

was wondering if layout id 11 is the correct one for this system, and that the pinconfigs etc are correct?

Ok, i will take a look and see if there is a difference.
 
I have X270 too (i5 6200U, HD520, 8G Ram, SSD Samsung 256Gb and the second SSD WD SN520 256GB NVME M.2 2242, removed Intel 8260 and used BCM94352Z). I had install 10.15.1 in my laptop and all full with SD card reader. I want to share 2 kext to use SD card (put in Clover/kext/other). Hope it work in all X270.

Hey @nhimanninh , welcome back!

That's great, I'll take a look at those kexts later today.

I didn't know Sinetek's project is still supported. Did you update the kext yourself?

Hey @Sniki , did the dumps from myself and @Feartech get patched in the latest AppleALC release?

Hi @nhimanninh , I tested on 10.14.6 tonight and the kexts didn't work for me.

I have another x270 being delivered tomorrow that I'll use to debug Catalina.

Did you change any plist values to get it to work on your laptop?

Can you guys share what drivers you have? I'm trying to make a boot disc again and I always get a reboot just before it finishes... not sure what to do. I have windows installed...
 
Also tried both opencore and clover... not sure what to do. :(
