So my headphones (Roccat Kulo) were running 7.1 surround, and my computer was REALLY dusty, so I unplugged it all, and cleaned all the dust out. I plugged it all back in, and I can't get it to change back to 7.1 Surround sound. The "Configure" button in my sounds menu is grayed out and i can't click it, and that's where I thought the option was. Help please!
