I did several test:
1)uninstalled the kext AppleHDA of Myron other but the result is the same
2)I changed the channel configuration midi and if I put the 4-channel audio back "normal" but it is fragmented.
My question is:
It is guilty of info.plist where there are pins configured?
Note, I have a combo headphone-microphone that is not detected so I would like an answer: if you AppleHDA, I try to pull the pin and configure it for my pc but I have to know if it's him.
I do not think the DSDT because the patch is standard.

Which layout-id are you injecting with DSDT? Did you patch for "IRQ Fix"? Which layout-id is used by the AppleHDA you're attempting to use?

 

[Pigreco]

I use layout id 3 in DSDT and in applehda i have to control. instead of fix IQR use an app that resets the audio after the sleep mode and works well "reset audio". as I see if I put the patch in DSDT?
The problem is that the microphone work but recorded bad, very bad like if the sound is slow e i hear a voice with bassboost.

I think the-darkoid's Dell is also ALC668...

IRQNoFlags() { 0, 8, 11, 15 }

Memory32Fixed (ReadWrite,
