Atomizer Issues with Daw

[Kev NEC]

(solved) Hi People,

It would be great if anybody can shed some light on my atomizer issue. I get an audio signal to go through my TI snow atomizer fine but when I open virus control on my daw (logic the output disappears. Here's some points on my configuration:

I'm sending audio direct into the jack inputs of the Virus ti snow.
i'm sending the signal direct out the jack outputs 1&2 of the snow.
My midi keyboard is connected to my focus saffire soundcard, not the virus snow.
As soon as I open virus control within Logic, the signal goes. Within virus control I select an atomizer patch and set the output to 1&2 (not usb 1&2) but nothing I do seems to get the audio back out the virus outputs.

Any help is of course appreciated. Cheers.

For info I managed to work this one out. It involved changing the output mode in the USB config utility to '3outs/no inputs' because the analogue input is disabled in any other mode.
