Two questions:

1) My little soundie isn't working as expected. I have one WAV on the board. No size problems. If I momentarily press the button, it sounds once. As expected. If held down, it plays over and over. Still expected. However, there is NO SOUND on the SECOND press. Turning the board off and on does nothing. I have to unpower the board to get it to make a sound again. Is it me? The board? What?

2) I noticed a previous post about wiring the board so the button doesn't need to be pushed to power it on. However, that question never seems to be answered. I don't want to have to press the power button. How do I wire it?

This board can be a bit quirky with WAV files. You might try converting the file to an OGG and see if that helps.

You can connect the PB pad to a microcontroller and pull that pin high for about 1/2 second via the micro controller to turn the board on, but there's not an easy way to wire this up to do that manually. Something has to send the signal to turn the board on, be it a button press or a digital high.

If you can build a circuit that sends a 3.3 volt signal for 500ms at powerup, that would work but I don't have a diagram that shows how to do that.
