Workaround

Not sure if everyone is aware of this but one point that is not explicitly mentioned in any of the previous reports/comments is that when the internal microphone is "not working" in Skype, the application is actually receiving its audio input from the external microphone socket.

So anyone who just wants a workaround just needs to plug an external mic. into the ping 3.5mm socket.
