So I logged into my computer this morning and there's no sound. My speakers do not show in playback. I've tried putting them in both audio jacks on the front and back of my computer. I've tried putting in my headphones. Nothing shows up. All I have in my playback is a device for my mic, and 4 duplicate devices that are all disconnected and are called NVIDIA Output. I've tried updating my audio driver. it doesn't work. I can't find my audio driver online so I can't uninstall it and reinstall it. In the device manager NVIDIA High Definition Audio shows up and there's no little warning signs or anything like that. it says it's running fine. My speakers do not show up in the devices.
