No sound Razer Kraken

Hello everyone! I have a problem since yesterday: my headset isn't working anymore. I wasn't doing anything in particular, but suddenly my headset stopped working. As you can see on the screenshot below, there is sound, but nothing in my ears. I unistalled and installed again the driver, tried the headset on an other computer but nothing worked. Do you have any clue that might help me ? See you soon ! Valentin.
