@JGoldman10,
Any or all of the following might fix it:
Go to Control Panel and check the settings for Sound to be sure your audio devices are still defined correctly.
If not, fix it. If so, try unplugging and replugging the audio devices so that the PC can detect it as a new device.
Power off the computer and reboot it.
If plugged into a USB port, move it to a different USB port.
