So I have a new Razer Kraken Pro V2 headset to replace my Logitech G430 set that stopped working right a few months ago, and I've already got a problem. When I first plugged them in (using the G430 USB adaptor), they played game worked fine, but then I went to tinker with the settings and now I can't hear any game sounds. I don't remember what I did, though. Any suggestion?
