I tried installing and using Nettalk to see if that would fix my lack of sound issue. Still no joy. However, I am still convinced this is a software issue, because when I hooked it up to my PC with a USB cable and then turned off USB on my PE, the speaker made a beep. A little later, I put an unformatted SD card into the PE and it made a beep.
Any more ideas out there?
