Hi there,

I am trying to run Chuck on Ubuntu 11.04 64 bit. When no input file is specified the standard "no input files" message appears. When trying to run an example I get the message :"[chuck]: (via rtaudio): no devices found for compiled audio APIs!". I've taken a look at the rtAudio.cpp file but can't make any useful deductions. I definitely do have a sound device and have successfully used portaudio on the same machine - Any help would be greatly appreciated!

Regards,
Raymond
