I patched AppleHDA according to your specific codec info, you should test and reply back.
I included a fully patched AppleHDA.kext as well as a so-called 'dummyHDA' kext (AppleHDA_CX20590.kext). If you choose to go with the dummyHDA kext, you should have vanilla/untouched AppleHDA.kext in /S/L/E as well as the binary patch to be applied to 'AppleHDA' in your config.plist, I attached the code you should paste to it... Also don't forget to apply the layout-id 3 to your DSDT as well as the IRQ patch.

Please test and reply back.
Thank You!! :)
I went the fully patched HDA + DSDT route, and the sound card is working perfectly! :) it recognises the jack and switches the input & the output accordingly!
I will try to figure out what verb commands & Pathmaps you used so I can compare it to what I managed to calculate as the guides are all somewhat mysterious in one or two steps. (at least to me)

Thanks again! :)

Internal Speakers?
Internal Mic?
Headphones?
External Mic?

everything works, with the small exception of the external mic.. as that works on "Line" level, so if I'm not mistaken, then I will have to change one verb command to make it "microphone" level instead of "Line"
for HDMI I would need to apply further patches (I guess) as hdmi does not appear on the list when I plug a HDMI source into it.

External Mic can work as an emic or line... but Conexant codecs are know to have issues with it, I have it disabled for my laptop...I say don't waste your time trying to fix it... just disable it like I did.

This also worked for my Lenovo E531 laptop on Sierra 10.12.

I used DummyHDA.kext in SLE and added the patch to Clover.

Thanks.

Hi,

just noticed that I can't control the gain control of the internal mic at all... doesn't matter if I turn it down completely or max the gain the input level stays the same. Do you possibly know how to address it?

thanks
