I can't select more than one audio device Audition CC 2017
I'm sure that this must be very basic, and I don't recall ever having encountered this in prior releases of Audition, but I'm currently not finding a way to specify different input and output audio devices in Audition CC 2017. Here is what I'm encountering.
When I go to Edit -> Preferences -> Audio Hardware, I see that the microphone I want to use is there --

However, I do not see a way to add a second hardware item for output. Clicking on Device does not have an option to add another device, and I can't see a way to do it with any of the other dialog boxes. In Audio Channel Mapping is the only area within Audition that I've been able to find so far that addresses different input and output audio devices, but both reference my microphone, and there does not appear to be an option to edit them --

Left to my own devices, I'm not able to figure this one out, and since my output is trying to play through my microphone, I have no audible playback of my sound tracks.
In other applications on the same PC, including Premiere Pro CC 2017, I am able to independently specify input and output audio devices with no problem, and playback works fine. Here is what my Premiere Pro Audio Hardware window looks like --

I'm running the latest version of 64-bit Windows 10.
Thank you!
