What devices do you use for capture and playback? The most suitable setup for
jack is hw:0,2 for capture and hw:0,0 for playback. Also make sure that your
samplerate in jack matches actual samplerate (see alsamixer).

Any recent alsa (1.0.15 and up) should work well. I have had 1212m nad now I
have 1616m cardbus. Apart from missing 24bit playback, higher samplerates and
some bells and whistles, these cards work pretty well with alsa.
