The netjack-slave does not have a soundcard attached to it. It connects to the master-jack which 'speaks' with the soundcard. You still need alsa_in/out to connect additional devices. You can also run two jackd's which connect to hardware directly and use jacktrip to connect the two jackd's .. and there may even be more alternatives.. Either way: Unless the sound-cards share the same clock, there is no way to _not_ resample. The above statement is true for any audio-interface on any OS. Sorry to disappoint you. As Joern outlined, audio clock synchronization can be accomplished by various means. You can pick up a soldering iron and follow http://quicktoots.linuxaudio.org/toots/el-cheapo/ or buy dedicated hardware that offers it. The technical term is http://en.wikipedia.org/wiki/Word_clock Check the recent thread on LAU 'ambidec:..' http://linuxaudio.org/mailarchive/lau/2010/9/18/173740 for a cheap solution.
