Kraken TE not audio very quiet after I unplugged them

I unplugged my headset to clean up my desk then when I plugged them back in there's no audio so I use the THX usb thing to raise the volume to 100 still no noise so then I google it and on Razers website it says to use the wheel on the side to raise game audio it is also at 100 now and I can barely hear my game. I checked and my default audio is on Razer Kraken TE game so I don't know what to do please help!
