When Using Ableton with splice,

When Using Ableton with splice, iTunes, or YouTube, I can’t hear audio from more than one of them at a time. I am wondering what I need to do (or buy) to get audio from multiple sources at the same time. It’s kind of a bummer because I thought I could sample splice loops and sounds while using Ableton and right now I have to use them one at a time.
Any help appreciated.
Thanks!
