Amarra 1.2 and Motu Ultralite - Output problem

[Kristo]

Hi friends..

 

I'm trying Amarra 1.2 in my MacMini but i'm finding a big problem...

 

i can't set the output to s/pdif in Audio MIDI Setup.

I explain, i can set S/PDIF but nothing exchange... my Motu Ultralite play only in the main output.

 

I try to set other analog output... but it's impossible too

 

that's a really big problem....
