I have Audio working via the ALC885 code I found somewhere on this board.
I used tarugas applehda patcher 1.20 .
I got the ALC885 code txt file and dragged it onto the patcher.
Sound is working from the 1201N speakers. I haven't tried HDMI sound output .
Which version of kernel do you use? (10.x? 32or64bit?)
I do what you say, but it doesn't work.
can you post your 885codec?
