To share the playback of sound during a Skype call, it's more effective to reconfigure your system's sound input settings so your Skype friends end up hearing what you hear over your computer speakers. While effective during Skype voice communication, your computer's microphone makes an ineffective broadcasting source when it's held up against another speaker. Many people have their computer sounds as well as voice played by default with Skype and they hate it to death, but it can be very useful for other people.
