I'm writing a manual on how to run the Saffire Pro 10 with ffado-mixer. 
Now I wish it was done because it's probably what you need to know how 
to route your sound with the Saffire LE.

I googled the LE and see it's much different than the Pro 10. But I'll 
be sending a link to the ffado-mixer/SaffirePro10 manual when it's done.

For now, in a shell, run ffado-mixer and see if you can route things 
correctly. Start with (not) running a recording program, but just 
routing directly through jack (QJackCtl's Connect window) and adjusting 
ffado-mixer's controls.

You can also sign up on the ffado-users list to ask questions:
https://lists.sourceforge.net/lists/listinfo/ffado-user

As always, you will want to search the archives first to see if someone 
already answered your question before asking the list.

Hope that helps,
Rocco
