[NEED HELP] Mic not working on Dell Latitude 3410, ALC236

[esteban1982s]

Hi!

I've successfully installed Catalina on my Dell Latitude 3410, and audio works fine using AppleALC method (ALC236 codec, layout-id=15), but whereas built-in microphone is shown on the input devices list, it stays unresponsive. I've tried every layout-id from 0 to 99 with no success. Also tried VoodooHDA method but built-in mic isn't even showing on input devices list.

I started to patch AppleALC myself following FOX1C tutorial but at some point I think I miss some information, or maybe its just too complex for me.

I've extracted this data, but I can't figure out how to go further.

 

NODE	PIN DEFAULT	EAPD	VERB DATA
0x14	0x90170110	0x2	10 01 17 90
0x19	0x411111F0		F0 11 11 41
0X1A	0X411111F0		F0 11 11 41
0X21	0X02211020	0X2	20 10 21 02

 

Attached you will find the pcidevices.plist exported from Hackintool, and dump codec files from Linux.

Can anyone give me some directions?

Thank you!
