What is happening, is that you are getting some "inf" or "nan" output
> #X obj 44 320 expr~ pow((int(pow(($v1*$i2) \, 3))) \, -3);
and "inf" or "nan" multiplied by 0 is "nan".
"nan" <-> 0 transitions appear to be audible from [dac~], which may or
may not be a bug. (tested with JACK and OSS on Linux with Pd-0.39-2 and
Pd-0.40-1, both from Miller's site).
See attached patch for an example.
