You need a splitter for the audio from the card to go to the mixers.
Won't that carry the same output to two channels rather than have two separate outs from different apps?
Yes but that did not sound like what you wanted to do. Windows does not work well sending audio from different programs at the same time and separating them. That is why you are having a hard time finding things, you need software that allows you to configure the audio source that it uses and then you can setup dual sound cards and use the output on each one separately.
This has been a long standing request from people https
