There isn't a routing tab in your M-Audio software?
It is separate from the mixer in the M-Audio softwares I use..

I think this may be where your answer lies..
Have you tried selecting a different output port? I do not have that exact device so I can't suggest alternative, but in the one I have if the 'monitor mixer' is used in routing things can get looped back thru.


I do not work here, but the benefits are still awesome
