Answer to: DSI microphone does not workSimple fix. On the font edge of the machine next to the headphone jack is the mic jack. For use with an external mic. Inside the jack there are two metal pins. They can become stuck in the "up" position. You simply need to bend the pins back down slightly. I used a sewing needle - being careful not to break the pins. Worked like a charm. All blowing games and voice commands now work again.
