Be smarter than the microphone. You click on the microphone button at the top left corner and it should be on. But it depends if you are using a laptop or desktop computer. If you are using a desktop computer there is no microphone. But if using a laptop, click on the microphone button on the top left corner. Then the microphone should turn on.
The Inspiron 571 is a desktop PC. As such it is unlikely to have a built-in microphone. However if it has a sound card, there will probably be a microphone input. Laptops sometimes have built-in microphones if they also have a built-in webcam. When present, plugging a microphone into the microphone/line-in input will disable the built-in microphone.
