It's intermittent, and I can't reproduce it. Note that I can wiggle the USB connector and the cable in my headset without causing this, so it's not a loose cable. That's the best I can say.
However, it's gotten worse since the beta version was released, and it's also worse when I'm running TeamSpeak along with Arma 3. (By "worse," I mean that it happens much more frequently than it did with the alpha version.)
