i've never noticed any problems with jack. basically, alsa runs on top of both cards. i tell jack to use card 0 (my audiophile) and it does happily. i still have card 1 available, so when i want to output to that, i tell the program to output to that one.
kinda looks like this:
jack -> alsa's ice1712 driver -> card 0
alsa'a ens1371 driver -> card 1
(just wrote that out to point out that the alsa driver has access to the card, not the other way around. technicalities/sorry if i mis-understood ;)
