[chuck-users] question about sporking

[Spencer Salazar]

This is a strange problem... perhaps you could send some small  
snippet of chuck source that reproduces the issue?

One idea that might be worth trying is doing an un-chuck on all of  
the shred's ugens from the dac before killing that shred.  If I  
recall correctly, the virtual machine should be doing this for you  
for free, but maybe something is going wrong with that.  Doing it  
explicitly is supposed to stop all audio coming out of the ugens that  
you unchuck.  For example, for a patch like this:

Blit b => LPF lowpass => dac;
BlitSquare sq => PRCRev rev => dac;

you would unchuck everything directly connected to the dac before  
exiting, like this:

lowpass =< dac;
rev =< dac;
