I have a question about my 'old' C64.  The sound chip seems 
to work ok most of the time.  However, right from the start
I've objected to it's decay performance.  When I turn off 
the gate (or use a sustain of 0), the sound indeed decays
to nothing.  But then it just barely comes back on.  This
happens independently with each voice.  The net result is
that if a program doesn't kill the waveforms or the volume,
an annoying ring/roar/hiss/mess hangs around constantly.

This effect was present on at least one other machine, too.
(I had a heat problem in my first unit.)  Has Commodore
fixed it in the newer units?  Does anyone know if there's 
something I can do about it?
