Audition and Scarlett 4i4 are not working together

Hi,

I just bought a Forcusrite Scarlett 4i4 Interface and I am completly unable to make Audition and the interface working together.

I choose Scarlett in the Hardware material in the preferences in Audition, but I hear nothing and when I try to record, my mike is not working, no soundis recorded.

Can someone help? (Also sorry if I make some english mistakes, my first and main language is french).

Great great thanks at advance!
