Actually this is caused by ASIO connection
Adobe audition allow using MME or ASIO
when you use MME you’re not connected directly through your audio interface
you’re connecting to windows audio then to your interface that is why in audition it will work
but actually there is a good trick ( hardware one ) :: connect your output signal to 2nd audio interface and use it with streaming apps
I find this a really good idea because your audience can hear anything you hear including monitor only inserts/ effects. and it will work regardless of protocol your interface is connected through…
actually if you see tutorials from universal audio they do this to let you hear (monitor- only effects on there console)
