On my A8N-VM then it's working with *init_verbs* commented,
max_channels 
set to 6 and num_dacs set to 3.
I haven't tried it, but if you're changing num_init_verbs to
1 then it 
looks like spec->init_verbs[2] = ad1986a_ch2_init; should
have 
spec->init_verbs[1] instead?

Just a couple of links. Bugreport which could probably be
solved if one 
of these changes was applied to the main tree:

https://bugtrack.alsa-project.org/alsa-bug/view.php?i
d=2478

I don't pretend to understand exactly what this change does,
but the 
attached patch does work and allow 5.1 output on an A8N-VM
CSM.
