Sound Queston (Microphone + Speakers = Loud noise)

Hi,

when i am talking on skype and have the speakers and microphone on there is a loud whistle sound coming. I need to plug in my headset in order to cancel that out.

How can I make so I can hold my microphone next to the speakers and no sounds comes?

You are most likely experiencing feedback. Try turning down the volume on your microphone, or move the microphone away from the speakers.
