Kraken v4 Pro

I just bought this headset and I can’t figure out what the point of this olde controller hub is for. I have to connect the head via Bluetooth to my PC. The controller hub is plugged into right port in the back my pc and when I’m in Bluetooth mode I can’t use any of the functions of the controller hub. I saw post online saying “Must be in hyper speed wireless, which when I enter this mode I can use all functions of the controller hub. Yay great… but now my system volume is muted and no matter what I do I can’t get sound. Doesn’t matter if I put my default device as “game v4 pro” or “chat v4 pro” still no sound and there isn't a “hyper speed wireless” device. So what do I need to do?
