Long story short, I turned on my PC today and my headphones just weren't working. I hadn't unplugged them, I hadn't messed with any settings or drivers, they just weren't working. They're HyperX Cloud Alphas and I was just using them last night perfectly fine. I tried switching from the case jack to the on board jack and still nothing. All I get is a quiet high pitched frequency. I plugged them into my phone and they work 100% fine no problem at all. The weirdest part is that they are no longer in playback devices, device manger, etc.
Edit: They now appear in the device manager, etc. however no output sound is working. I'm not using them from the rear port.
