Thanks to Raymond's advice I was finally able to make the sound come out 
of the copper part of the spdif/side surround jack. I am pasting the 
diff created with hda-analyzer, please let me know if this gives you 
enough information to add proper 7.1 sound support for this laptop.
Here is the alsa-info.sh with all jacks playing sound:

Of course, there is still no specific volume control for the side channel.
