I have Turtle Beach x12 headphones which i've had for a few years. I hadn't played my pc in a couple months and when I went on the sound cut out after a few minutes and hasn't come back on in weeks. I don't have speakers, so I'm basically screwed. I'm like 75% sure it's a problem with the headphones and not the computer, but before I buy a new pair I just want to see if there is something I can do on the computer to be sure.
