There should be a popup box asking when you plug in the mic ? If not, go to Start/Control Panel/ Sigmatel and see if 'allow popups' box is there. And plug in the Mic , there will be a configuration question answer it and then try again

If the above thing doesn't work then try the external mic test in the audio section of Dell Diagnostics . To do that you should restart your pc and when it start boot up and hold down f12. you need to 'Diagnostic' from the boot menu.it will run a pre-boot for 3 or 4 minutes , it wil test some beeps and tones through the system speaker but it will not but it will not test the rest of the audio hardware, so you got to wait for dell Diagnostics run after the pre-boot tests finish, when there will be a instrumental piece of music played like drums then you have only run the Dell Diagnostics if not then it is just pre-boot assessment test.
