[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?
