unless you have identical cards or a house clock driving them, you will need to resample to keep them in sync. jack_diplomat does this with jackd's running at different hardware samplerates (say 44117 and 43986). there might be similar magic you can do via asoundrc.. but afaik its resampling features were really designed for lke 96000->44100, more than 44117->44100, so might not solve the unique clocks proplem...
