[linux-audio-user] JACK of two Cards

Hey peeps, So, I've been using jack with the onboard audio stuff in my li'l cube (snd driver = snd-intel8x0) and that works. And I've been recycling/parting-out older or broken systems and found a PCI audio card with an ESS Maestro-1 chip, which after some trial and error, discovered it needs to use the 'snd-es1968' snd driver (not snd-maestro3). So I put the card in, reconfigured my audio, both cards are seen, all the modules are loaded. and then I go to start 'JACK' and... well, each *one* works (although there is a different problem with the Maestro-1 I'll save for later) it seems to let me use *either* one or the other but not both. What I really want is to be able to use the inputs of both cards for multi-track recording. Really, I'm just trying to get the stereo keyboard separated from the stereo vocals, that's all. Seems like it should be no biggie, but... not. So, first off, is this possible? I mean there *should* be a way, right? any clues for me before I go bangin' my head on a wall? ;-) Thanks in advance, ~Jos~
