It seems in premiere there is a setting that makes you select the output of audio between the i/o on your video editing card/breakout box vs the one on your sound card. You have to choose the one you want. It seems like there is a toggle selection on one of the menus but I am not in front of it now to tell you how to get there. You've probably found it already since the post was some time ago.
