Thank you.
I ended up missing an entry in /etc/ude/rules.d/alsa-*
(the devices were present,but in /dev/* instead of /dev/snd/*

Now that i've realized udev
was not creating the device, everything
has changed(back to the beginning with this one)

I'll let you know if I find anything
interesting(hopefully).
