you are confusing things here.
its not about wordclocks being in sync. if your wordclocks are in sync.
you dont need alsa_out.

but most likely your wordclocks are not in sync. this means your
soundcards run at different drifing samplerates, and one soundcard will
consume a different amount of samples per jack cycle. but jack is
feeding period samples each cycle.

first try using -q option set to 0 because that will use linear resampling.
reducing the value of the -s option (default 256) will also improve cpu usage.
but might yield worse performance of the algorithm. it depends a bit on
the soundcards you are using.
