This is probably the most frustrating computer problem I've ever had with a computer. For months now any microphone I use on my Alienware 13 is not being recognized in my device manager. Whenever I'm in Skype calls with people, they can only hear me through my computer mic even when I'm using a headset with a mic. I've tried showing disabled devices, downloading drivers, using different mics, and basically anything else I could find over months of searching.
