Got the same problem. Was very happy about finally getting sound to work, but noticed my microphone didn't work. Found a solution just today that it actually works (although I have no idea why this works for my mic, it sounds like it shouldn't), if I plug it in on the other side of green "entry" which is a lightblue I think (not at home atm), then I plug it back into the pink/red for microphone and it works.

I accidentally found it out as I thought I should try to use microphone in all other entries and see if it for some odd reason works (I am no sound guru, those who are probably are laughing at me now as I suppose its impossible ).

However this is not a solution Im happy about, replug the mic to lightblue then back where it should be each time I turn on my comp.... Also, this "replugging" for some odd reason messes up the volume, so when I speak it just gets louder and louder until the other person on skype throws his/her headset of

Still searching for the magical solution.
