Hi,
We just bought a fleet of UFX II.  I've used it before quite extensively, but not the type of studio I'm installing the new ones in (a school).  I'm quite confused about the interface presents itself CoreAudio apps, and in which mode:

1.  I've only needed to mess with AudioMIDI Setup 'streams' occasionally for another interface, so they're a little mysterious.  The UFX allows a choice of streams that include only *some* of the inputs (Analog 1-8, Phones 9-12, etc.).  I'm not sure how meaningful this is to other apps, and what use in AudioMIDI Setup.  Pro Tools allows any I/O choice, regardless, but the input choices from some other apps we need (Audacity, QT, etc.) are unclear– "Default", a list of input numbers- some of which don't work, etc.

2.  Is there a particular way the UFX driver handles setting default I/O for apps?  It seems to default to analog 1-2 (at least on the output), but we don't always want to use that.  There are a few words on it the manual, but does that change with its different modes? 

I know these things can depend on the app, but the app has to work with what the UFX driver gives it.

Hope that was follow-able, thanks!
