I'm building a consumer-oriented internet appliance.  A beep sound would be useful for error notifications.  I don't want any audio other than this.

I know how to flash the LEDs.  How can I make a beep sound.

Any ideas?

You might be able to attach a DC transducer to one of the GPIO pins and excite it through code.  Not the best solution; but, it could be really cheap. Smiley
