hi
@Leesureone thanks a lot for your reply.
I tried your EFi as per Post #903 and exactly the same cracking and general lack of quality is what happens to the audio through the headphone jack port.
HDMI Audio works even without FakePCIID.kext and FakePCIID_Intel_HDMI_Audio.kext.
HDMI Audio works well in fact, is headphone jack audio that works really bad.
As I said using your EFI from post #903 makes no difference. I tested the whole EFI including your SSDTs.
Do you have idea why that happens?
Should I update the Bios to the latest?
