While in-game, I realized I wanted to use my microphone. I unplugged my speakers from the back of my PC and plugged in my headphones to the audio and mic input. Upon doing so, I lost all sound. Even after plugging in my speakers again, the sound did not return until I restarted the game. Works fine as long as my headset is hooked up before I launch, but all audio is lost when unplugging speakers.
