[alsa-devel] No line out on latest Mac Mini
I posted this to the alsa-user list a couple of weeks ago but did not get an answer
I've been trying to get analog line out to work to headphones or powered speakers with the latest Mac Mini, but so far the best I've managed to achieve is to get the internal speaker to work. Line out works with the Mac OS.
I've also tried the HDA analyser mentioned here:
http://www.alsa-project.org/main/index.php/HDA_Analyzer
but no matter what I do, there is no way to get sound from the line out jack to headphones or powered speakers.
I'm guessing I need one or more obscure options to load the module snd-hda-intel, but nothing I've tried so far has worked. The kernel documentation does not mention the mac mini 5,3 the Intel Corporation 6 Series/C200 Series Chipset nor the combination of Cirrus Logic CS4206 and Intel CougarPoint HDMI - does anybody know where I might find more details?

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

Jérémy.
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.

Thanks - I had a go at making a patch, but couldn't get things to work.
Is there a howto anywhere?
Otherwise, I guess I'll have to wait for a later version of alsa...
