Is there such a thing as a "silence signal" in Jack? In the real world
obviously not, silence is the absence of sound pressure, but in Jack shouldn't it be
possible to fill the channel with 48 kHz (or whatever) of zeroes? And more importantly,
does anyone have an easy way to do this??? (Or is it already being done?) I am hearing
some faint things in my output that I cannot explain, and a 'silence generator'
(if the concept in fact makes sense) would help me figure this out.

Just start jack: it "outputs" silence so to speak. Jack clients output is
then added to the silence, when you make a connection.
So to speak: there is some extra processing that can be avoided in the
implementation, but that's not what the question is about here now :)

if for whatever reason you need a jack-port that provides explicit silence:
cat /dev/zero | jack-stdin silence
but you may just as well leave the target port disconnected, as Harry
said it's silent by default.
