For that, you must use the sync of one card for the 2 cards. It mean toremove the quartz on one card and sold a little coaxial cable from the quartzon the first card to the removed quartz on the second card. Such quartz have 3 pins: input, ground and output. The shield of the coaxialmust be connected on the ground of one card but free at the other extremity(it will do a ground loop if you connect both ends), the central wire must beconnected between the output of the quartz to the input of the removed quartz. Done blame me you your(s) sound card(s) goes broken after such a modification.(It is impossible to know if it will work and if the IC on the first sound cardwill be able to drive 2 cards without to try it...) Note at the parasiticcapacitance of the coaxial cable will modify the frequency a little, so use alow capacitance cable.
