Hello, If you really just need snippets I would suggest not using jack for recording them. You could for example create a script which starts arecords for both/all cards at (almost) the same time. This way you wouldn't get the distortion created by jack correcting sync problems. Syncing these samples in a multitrack would be a breeze if you create an impulse -type sound which is recorded by all cards (i.e. clap your hands, turn mixer on...). You can also do an impulse in the end of the recording to measure the drift between the cards. This data would allow you to precisely correct the drift by using resampling. The distortion created by jack could be as bad as one clip per period*buffersize samples. I don't think that will be acceptable for anything, but I haven't tried this so it's probably worth trying out if you really need to do your recordings in a RT environment.
