I don't have a 1724 (I have a 1712) but it looks like your two sets of
inputs have their own PCI bus interface. (unlike the 1712) So the first
thing to do is:
 arecord -l

That should tell you if they are both the same sub device.

Having said that and looking up "quartet" via google... is this a USB
device? The ICE1724 looks like a PCI chip... though I suspect it could be
used through USB... but in that case why not use the VT1730? (maybe age,
the quartet looks like it has been around for a while) The 1724 does match
with the port count though.
