You're looking for bio2jack, a wrapper library to convert oss apps.

Look at /proc/asound/oss/devices to get the oss device number(s) for your
second card, then open /dev/dsp<x>, where <x> is the first pcm device of
the second card and then the second card will play.
For that to work, sound-service-1-3 must be aliased to snd-pcm-oss in
/etc/modules.conf.
