Recently I finished building my PC, and as I was plugging in my peripherals I realized my headphones don't make any noise. I got the harminoq pro, and they just have one usb cord, which I plugged in. I know its not broken because the LED lights are lighting up, I just cant get any sound out of it! Forgive me if this is a stupid question, I'm kinda a noob at all things PC related, and so any help would be greatly appreciated.
