[ref]Mirone[/ref], I beg your pardon. I solved my personal problem with an external mic and shared the result. If you want, you can merge it to https://github.com/acidanthera/AppleALC that's it.

Yes. It works with layout=3 injected via Clover's Device Properties. Your patched AppleHDA and layout=2 is working without external mic. And AppleALC, layout 3 without the patch above behaved similarly. The patch enables getting sound from a device but hda-verb 0x19 GET_PIN_WIDGET_CONTROL 0x00 returns 0x20 by default for both 0x19 and 0x1a. 0x1a works regardless a value set. I wonder if there's a possibility to set 0x24 for external mic via pin config in AppleALC or so. In order to have MacOS partition completely untouched by hacks and keep everything custom on a EFI partition. P.S. I was right. It is possible. Here's the full patch for AppleALC which enables external mic (LineIn) on cx8050 without codeccommander and other workarounds. I basically appended the verb command "01970724" to set 0x24 on 0x19 into pin config. May be it makes sense to make a pull request. The sound from ext mic is quiet though, even on max volume but it's more about the layout and platform, I think. cx8050_pins.diff.txt

No. It doesn't work either. It is the same as your AppleHDA patcher does and the same as your patch in the AppleALC project does. It doesn't receive the actual audio signal from the combo jack. CodecCommander and hda-verb work fine in terms of changing and reading values. Something wrong with the hex/base64 in patching the binary here https://github.com/acidanthera/AppleALC/blob/master/Resources/CX8050/Info.plist I guess. P.S. I was right. This patch gets external mic working. But hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x24 still has to be executed. It seem that there're no options to automate it without userspace tools or without non vanilla kexts in a system partition. cx8050.diff.txt

Hello, I've got almost the same problem with an external mic, combo jack on CX8050, 14f11f72, an Asus laptop. Everything works except the external mic via the combo jack. Neither AppleALC (from GitHub) nor your AppleHDA Patcher (1.9) work. "Line In" appears in the UI but doesn't receive input sound from a connected headset. VoodooHDA works but doesn't support HDMI audio, hda-verb on 0x19 and GET_PIN_SENSE detects an inserted jack. According to what I found in the internet related to this codec, it isn't only me who has this problem. codec_dump.txt
