Live microphone and Amorok, is it possible?

Bit of a dumb questions but, Opensuse 13.2 KDE desktop, I have the typical programs such as Amarok to listen to my music, some of my tracks I like to sing to, well who doesn’t. But wearing headphones I apparently sound terrible, to others of course. Is there anyway I can have an open microphone so I get live mic mixed in with the headset.

I do tend to use a USB camera mic for skype and it is always connected.

Is the a terminal command I can run when I want this?

Should possibly say that when I check with skype options I seem to be running Pulse audio server.
Cheers
