To be nasty, 0dBFS... but that's not the answer you're looking for. JACK's
audio is floating-point between -1 -> 1.
Hence outputting all 0's is silence. If you scale your output to be between
-1, 1 then you've got what you want.
Note that inter-sample peaks in high frequencies will still go beyond your
DAC's range, so there might be clipping in hardware... but I'm not too
certain in that field.
