Hi, I am new to Linux. I just upgraded my Ubuntu 12.10 setup to the Ubuntu-Studio version. Now I can't get Skype to work. Firefix audio works just fine, but Skype has absolutely no sound. It says when I try to do a Test Call it says "Problems with Audio-Playback".

I think the problem lies with Jack. When I try to start it, I get this message:
