Yeah, there was an answer to this on the mailing list from a couple months back.

That is the sound of the speaker rapidly switching from somewhere in the waveform to nothing. You need to add a decay to your impulse so the amplitude drops off before removing it from DAC. You can do this with an envelope or ADSR or something ... see http://chuck.cs.princeton.edu/doc/program/ugen_full.html#ADSR

This causes clicking:
Code:
for(0 => int i; i < 20; i++)
{
 SinOsc s => dac;
 220 => s.freq;
 180::ms => now;
 s =< dac;
10::ms => now;
}


This sounds ok:

Code:
for(0 => int i; i < 20; i++)
{
    SinOsc s => ADSR e => dac;
    // set attack, decay, sustain, and release
    e.set( 10::ms, 8::ms, .7, 20::ms );
    220 => s.freq;
    e.keyOn();
    150::ms => now;
    e.keyOff();
    20::ms => now;
    s =< dac;
    10::ms => now;
}
