Perhaps skype needs to add a menu similar to audacity's where you can choose the mic....

Couldn't agree more, it's incredibly confusing at the moment.

Skype does allow you to choose a mic input but only if Pulseaudio is not running. When pulse audio is running the assumption is that pulseaudio chooses which inputs and outputs to use for which app and remembers them.

When you have KMix open, there should be, on the inputs tab, an entry for Skype. Right-clicking somewhere on this ought to bring up a menu which will allow you to choose which physical input to connect to Skype. It's far from obvious but it is there somewhere.
