Using my Mic instead of playing Audio File

[jrand63]

Whenever I press F1 (or whatever key I have binded hldj_playaudio) to, it uses my Mic like it would if I were to hold V and talk. Therefore I'm transmitting my own voice into the game instead of the audio file. I've looked around and haven't seen any solutions on this. My audio files seem to be fine. I urgently need help, all responses are appreciated, thanks!
