Thanks very much. I do know about zita-a2j any may end up using it for recording smtpe through onboard audio, at least as an experiment, but for standard audio I would like to avoid resampling whenever possible. Also, maybe pure superstition, that a2j attached soundcard always feels as just being second best, not treated equal.

However, if I may re-ask, as it has not been quite clear to me: While alsa seems to be capable of handling two cards that way, would this also work for jack or would jack refuse to fail for this trick?

if the ALSA layer behaves, JACK has no idea what is going on. But this does require that it manages to start all N cards within a 1 sample timeslice. Theoretically, it should be possible to do this in microseconds.
