Minimal example not working.
Hi all, I'm just trying to get a minimal example going. I've currently got this: sinosc s => dac; 440. => s.freq; while(true){ 1::second => now; } When I run it I get: [chuck]: RtApi: no devices found for given stream parameters. [chuck]: cannot initialize audio device (try using --silent/-s) I compiled chuck to run using linux-alsa and I'm running it on an Apple iBook running Debian Linux. ALSA is know to work correctly on this machine. Any help appreciated.

Hi Erik! Welcome! (and thanks for libsndfile!)
When I run it I get:

This may be a sample-rate issue. ChucK defaults to 48000 Hz on Linux (only), but if you are running linux on Mac hardware, perhaps only 44100 is supported by the soundcard? Try: %> chuck --srate44100 foo.ck or %> chuck -r44100 foo.ck Let us know if this helps. We have yet to add autoconf support (which the great Stacken folks have already written for the previous v1 release, but we haven't glued things together for v2 yet). Best, Ge!

No problem :-).

Much better. Now I get a nice clean undistorted sine wave, but when I hit control-C I get: [chuck]: cleaning up... Illegal instruction Not a major problem but it could be a sign of a problem elsewhere. So, is there a way to tell chuck to use a different default sample rate other than the command line? A config file maybe?

Hi Erik and all,

Yes, our termination code is even more suspect than the rest of chuck, especially on linux. How often does it happen? Our (unix) signal handling is currently rather uncoordinated.
So, is there a way to tell chuck to use a different default sample rate other than the command line?
Unfortunately, not without modifying the source. A config file (or perhaps some environment variables) would be great. We will priority boost this. Best, Ge!

Every single time I terminate chuck using control-c.

Thanks, much appreciated.
