This is the nutiest thing. I plugged my new USB headset into my laptop and it worked fine. I unplugged the speakers from the new computer and plugged them into my laptop, and they worked fine. I then plugged the headphones into the new computer, and I had sound. Next, I unplugged the headphones and then plugged the speakers into the front jack, and they worked (screen popped up to confirm I was using the front jack). Moved them to the rear of the computer, confirmed I was now using the rear jack, and they didn't work. Moved them back to the front, and they work.
