I am using an external Web-cam with a build-in Microphone. When I am using Skype or some other Software it doesn’t recognise the Microphone automatically. So I always have to activate it myself in the Audio Settings. How can I avoid this and set it as default Web-cam. This PC doesn't have another Webcam or Mic. And the Web-cam is always pluged in. Ubuntu 12.04 beta with latest updates (I also had this problems with 10.04) Logitech, Inc. Web-cam B500
