Hi, i have an imac 12,2 (2011) and i had to change GPIO with hda_analyzer to get some sound on line out.

Thanks - I see something like this with hda_analyser:
Global Input Amplifier Caps-> <- Global Output Amplifier Caps
GPIO out-dir enable unsol sticky wake data [0] [1] x x [x] [2] [3] x x x
..where [1] data enables/disables line out and [3] data enables/disables the internal speaker. [1] data was not checked and doing so got things working - a big thank you for this.
Line out continues to work after closing hda_analyser, but do you know what it actually changes so I Can make it permanent across reboots?
A patch that applies to recent kernels : https://gist.github.com/1306112
The pincfg won't probably apply for you -- but it show how you can hack something.
