i compiled the latest from miller's site:
http://msp.ucsd.edu/software.html

so i have 0.45 working, audio is fine;
the api/specs/docs on the GPIO and analog sensor pins on the UDOO are
MINIMAL.
i'm working on getting them going.

been using the built-in audio;
it has 1/8" in/out in addition to the HDMI

absolutely.
the GPIO setup on the UDOO is the same as the PI (i.e. the is a special
folder with a subfolder for each pin and the params for each pin is a file.
the GPIO pd extern that miller has (
http://msp.ucsd.edu/syllabi/206.13w/index.htm) should work just fine; i'm
only waiting for the pin-numbering diagram from UDOO folks...
