do you know i cannot actually remember!
for some reason when we were first setting this stuff up x11 wouldn't
open the gui properly, but we installed xcode and then it did.

still unexplained. we're logging in as root via ssh as well.

is there an HDMI audio input too? that would make the Pi quite
appealing for what we're doing

we used the Griffin iMic really successfully (and you get pretty clean
audio) although the extra board just made the unit too cumbersome for
our needs.
