Can't get any audio out

Welcome to the forum!
It's hard to say much because you don't tell us how you have things set and connected. Are you talking about recorded audio or MIDI, or are you just trying to record without success? What have you selected as your recording and playback timing master and what drivers you are using?
First of all, do not use the Realtek, have only Tascam selected in your preferences-dialogue, and use its native ASIO drivers (I'm sure there are such).

So, please, what about answering my questions and telling how you are doing things?
You must understand that we can't see how your inputs and outputs are on the tracks, what you have selected in Preferences etc. 
 
"It says they're there"... What are where? What buss? How do you have your tracks set? What "audio interface drivers"? ASIO? Are you using a soft synth with your keyboard or are you hearing the keyboards own sounds?
 
You can't get audio to come out - does it mean you can record and see the waveform on the track, but you can't hear it? Are the level meters responding to signal?
