There it is in bold:

   Word Clock Sync

   To run multiple cards the word clocks need to be
   synchronized. With two Delta 1010 cards this can be done by
   connecting the word clock output on the first breakout box to
   the word clock input on the second box. Alternatively, they
   can be linked via S/PDIF (connect the S/PDIF output on the
   first card to the S/PDIF input on the second card).  Then use
   envy24control from the alsa-tools package to set up the first
   card to use its internal clock and the second card to use the
   word clock input or S/PDIF. Cards without word clock in/out
   can be synchronized via the SPDIF in/out.

How embarrassing.  I need to slow down a bit and read m o r e
c l e a r l y.
