Either you need to clear you NVRam or you are manually entering this in your boot arg during boot

-disablegfxfirmware -lilubetaall keepsyms=1 debug=0x100 alcid=1 vsmcgen=1 

 

alcid=1 is wrong, should be 56 as you have it in the Config file. Since I don't see the above arg in the Config file, I only assume you need to clear the NVRam

hey @Jake Lo

 

I finally fixed Audio, well, the internal Audio only...

The speakers and microphone are working PERFECTLY, they are loud and very high quality, I am impressed, but when I plug headphones they are detected and working, but they work poorly, I barely can hear something...

I will post my EFI here from my Google Drive  if someone needs it, BUT ITS INCOMPLETE !!!

I still didn't tried Audio on HDMI, but at least Video is working when I did the test some time ago.
