OBS AUDIO ISSUES- Hear zero audio gameplay from my stream and recordings, uses headset mic to record and stream. Can still hear myself, but not the game play.

[RoryValintine]

I'm getting no sound (OR BARLEY ANYTHING, SOUNDS LIKE A SOMEBODY DROPPED A TACK BUT LIKE HALF THE SOUND, LIKE NOTHING) of my game when streaming and recording on obs.
I have the most recent version before December 24th, 2016 of OBS.
I just went through all my audio and got my speakers working and got my headset working.

I'm somebody who uses a headset to use my mic to chat and to hear my game play with. My headset is my default device to talk and to hear things come in and out.

Right now all I can hear is me talking in my recordings, but little or zero sound of the game play on the recordings.

Need some major help here !!!
