Firs of all thanks
Second, what is the benefit?
Third I just generated ssdt.aml and ssdt-1.aml and put them in the patched folder with DSDT.
I got one error, it said Board-ID doesn't support ivy bridge but I generated anyway.
Here is the test result I hope I did correct.
Intel i7 3770K
I just direct updated to El Capitan and now I have sound issue.
Internet browser and some application like itunes, MPlayerX, don't have sound.
Logic Pro X, Studio One 3 have sound.
I can't find the problem, any help please?
