Adam, I use the AQ Dragonfly just fine with Ubuntu. It worked in 13.04, 13.10 and 14.04.
I use it with Guayadeque, which allows specifying the playback chain to a reasonable degree.
The device I connect to is plughw, because as you note the Dragonfly only accepts 24 bit data.
I have never tried > 96kHz but it works fine at 44.1, 48, 88.2 and 96.
I suggest you try the plughw device. Also you might try it with aplay and some wav files before you jump into mplayer.
If none of that works for you, I will carefully inspect my configuration so that you can tell what is different.
Good luck!
