Question / Help Game Capture not recording game audio?

[Foon]

Hey guys when I use window capture and monitor capture I get audio with the 64-bit client but when I use game capture I get all the noise from backround applications like voice chat and winamp but not the sounds from the game I'm playing. I used the directshow audio source plugin to add my stereo mix as an audio source and that gave me the game sounds but it also played any other sounds like voice chat or my music player twice over causing an echo. The only audio devices I'm able to select in obs settings are default , speakers (claro halo) , and S/pdif pass-through device (claro halo). What are my options here? This isn't just for one specific game but all of the ones I've tried.
