The routing gui isn't good at the moment. I have a new widget in the pipes, 
which should make it easier. But still the routing possibilities you have 
there are more then what the other os's driver suggest you. Which makes it 
easier to get stuck...

What jack presents is different then from what you see in mixer/router. The fw-
connection from the computer to the device is not hard-coupled to the inputs 
and outputs of the device as the names you see in jack suggest. In fact the 
fw-connections are just more inputs and outputs in the router which can be 
connected everywhere you want.
The router in the dice-devices is quite versatile: You can route any incomcing 
signal to any output. For example you can use that to change your saffire pro40 
into a "simple" adat/analog converter by routing the analog input to the adat 
outputs and vice versa. Which will then even work after you unplugged the 
device from the pc:-)
Note that the mixer is also "just" a bunch of inputs and outputs for the 
router. So you can actually make the audio go from the analog inputs directly 
to the fw and back from fw directly to the outputs without any signal crossing 
the mixer.

I can fix you up with some docs about the dice next week...

Have fun,

Arnold
