Hi! Recently, my microphone stopped working. One day, tried talking into it with a friend on skype, and it didn't work. At first I assumed it was a problem with my microphone, cuz it's ancient. I reinstalled skype anyway due to other problems with it, and also got a new headset. I can hear perfectly with the headset, but in Sounds it says my microphone is "currently unavailable" and I'll get a message from Skype saying it can't detect a soundcard from my computer. I am unable to set my microphone as default as those options are grayed out.
I'm not sure what to do here, I suck with computers.
Additional info: Computer's running Windows 8.1. There were no changes made to the system to my knowlege. Troubleshooting does nothing. I don't use the internal microphone because it picks up the noises my computer makes (e.g typing, fan running, clicking, whatever) and no one can hear me over it. Drivers are up to date, also tried reinstalling them.
I have tried turning it off and on again. I have tried unplugging it and replugging it. I've tried nothing and I'm all out of ideas. Thank you.
