Can't make working the output OUT1

[fantasia]

Hi there,

I've got a Virus TI Snow and I use it with Cubase 5 and my soundcard is a MOTU Ultralite MK3
Due to the limited 3 USB outputs, I would like to use analog output OUT1 L+R , like this I'll be able to use 4 different sounds on 4 different mixer channels at the same time insteed of 3

I have connected the stereo jack cable from the OUTPUT of my Virus TI to the INPUT 3-4 of my MOTU soundcard, then in the Total Integration interface, I select OUT L+R insteed of USB 1,2 or 3 and after that I don't know what to do, I have no sound.

Hope you can help me.
