Win 7. For using the 2i2, I set Systemwide as the default, the 2i2 was enabled, everything else was disabled. The AP was set for ASIO output with the 2i2 selected (it does not give the option of Sonarworks, and the apps guy at AP didn't know how to do that, either). No good. So I used the balanced analog output of the AP running into the 2i2 line inputs, with Systemwide set for the 2i2 as its output. Nope.
And of course, the Systemwide did not give the AP as a selectable output.
I bet there's something easy to do that one of the computer-savvy types will know about.
edit: I was looking at this as a possible solution. Opinions welcome.
