Hmm, so just for my own understanding of this, if
let's say 2 soundcards A
and B lack sync between themselves, yet are being fed in appropriate
intervals small buffers of audio data from JACK, what is preventing them
from staying in sync?
The slower card will have to be fed something other than the source
material from time to time to be able to catch up to the faster one (the
"source" is coming at only one speed from only one place and going to
two different places that need to be fed at slightly different rates).
The "something to be fed" will be probably silence, that is, a click :-)
The size of the buffer and the amount of drift between cards will
determine how often you get a click (if the software would support doing
this at all, of course).
