Hardware: Focusrite Scarlett 2i2 Gen 2, Audio-Technica AT2035

My microphone works correctly for Teamspeak, Shadowplay, and any other recording software. Unfortunately in this game it does not work at all. I have bound both of the PTT buttons and can see the symbol indicating it is trying to transmit, but nobody hears anything. I have tried adjusting the mic volume,checking for driver updates, even talking louder and nothing.
