Can't record mic and game audio at once!

[gaylordschuster]

I have my mic (Behringer C-~1) connected to Alessis io2 interface which is connected to PC via USB. When using default configuration i hear game audio only and when changing it to my microphone i hear my mic with no game audio. The video is fine, the problem is I have to use additional things like Audacity to record my mic. Is there any way to record both of audio layers?

Make sure to enable both Primary and Secondary Sound Device options.
