Need Help with Digital Ins And Outs

Thanks for the help DT. I appreciate it. Yeah, Adobe Audition does't seem to be straight forward, same with cubase sx3. I figured out Cubase LE and SX3, now it's just adobe. I don't see anything in Adobe that will allow me to switch buses or inputs. It ONLY seems to recognize the stereo ins. It will allow me to switch between interfaces though.
