Im using a Mac and it has a microphone in it, but i cant figure out how to turn it on for Duolingo. how do i get this to work?
This is a problem I have too. Apparently Flash says there is a way to allow websites to use the microphone through System Preferences panel. If you cannot find it, then try using this interface here: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager06.html
You may get an error about an unresponsive script; press "No" and the applet will load. Using it you can search thru websites and add/remove permissions as necessary.
Best of luck!
