hi everyone, i'm trying to get chuck up and running on an EPIA Nano- 
ITX box running Linux. i'm a total Linux newbie, though i'm  
reasonably competent with unix. i've got chuck compiling fine, but  
when i try to run chuck, i get this:

 >>>>>
root at bossa:~/chuck_dev/v2# chuck examples/basic/foo2.ck
[chuck]: (via rtaudio): no devices found for compiled audio APIs!
[chuck]: cannot initialize audio device (try using --silent/-s)
 >>>>

and chuck --probe tells me this:

 >>>>
root at bossa:~/chuck_dev/v2# chuck --probe
[chuck]: (via rtaudio): no devices found for compiled audio APIs!
[chuck]:
[chuck]: ------( chuck -- 1 MIDI inputs )------
[chuck]:     [0] : "Midi Through Port-0"
[chuck]:
[chuck]: ------( chuck -- 1 MIDI outputs )-----
[chuck]:     [0] : "Midi Through Port-0"
[chuck]:
 >>>>

i get this with versions of ChucK compiled for both Jack and Alsa.  
"alsamixer" works and seems to indicate both input and output devices  
(the board has built in audio I/O). also, supercollider (which uses  
Jack) seems to be ok. is it possible that there is something simple i  
need to do with the audio system, like specify a default output or  
something, for Chuck to find what it needs?

thanks!
dan
