[chuck-users] Multi-channel weirdness (mike clew)

[Perry Cook]

what does 

chuck —probe 

print out?  Maybe you’re connecting to the wrong dac??

For reference, here’s an invocation script I used last time 
I did a multichannel performance:

chuck -c8 -bufsize2048 -in2 --dac1 --adc0 INIT.ck

That would have been an older version of chuck, but it worked then.
