Webcam and sound not working

I feel like either this is a unique issue or something major has gone severely wrong but for whatever reason my webcam does not work. I've tried different browsers, clearing stuff out, plugging in an external webcam, and even a different laptop entirely but still I do not show up. Any help please would be appreciated.
