JACK will only handle them via alsa pretending that they are a single
virtual card. Some people have had problems with this, the sync has to be
very tight to avoid problems, and it isn't always on consumer cards.

On the Delta cards it requires some driver support IIUC, and I dont think
M-Audio released the specs for the link.

If the link is wordclock based, you should be OK.
