Just solved mine !!!
what you do is right click the audio options down bottom right, click recording devices, if your mic isn't there right click in it and select show disabled devices, if it then comes up right click on the device and click ENABLE!!!
took suprisingly long for me to find that.
i tried that and it did not work for me.............. my computer at one point couldnt find its own hardrive im thinking it had something to do with that. someone help?
thank you so much!!! ive tried to many things!! im far away from my family and skype is all we have! and they couldnt hear me! now it works! life saver :)
