Ok, ive been all over looking for a solution without any luck. Here is the problem. When streaming and or recording in OBS, there is an echo of gameplay, mic sounds ok, but bad echo. If I turn off the volume for the mic via OBS, gameplay sounds great, yet no voice for mic.
First the hardware:
Xbox One
Astro A40 with Mix amp pro
Black Magic Intensity Pro capture card
Here is the log from OBS.
Now, here are the sound settings for OBS and PC.

Changing the speaker volume to 0 does nothing. Only when the mic volume is turned of does the game echo go away.
