Need Help with Sound & Remote

I'm getting a lot of feedback from the Intelligent Sound Module and I'm having trouble assigning sounds to the ports. Can someone help?

My setup:

Coin Cell Battery Pack with On-Off Switch connected to a 3-Port Expansion Board

That board is connected to the TRUNK11 and another 3-Port Expansion Board.

The second expansion board is connected to the sound module and controller board.

I did not delete the stock files from the soundboard, and I added three short MP3s.

Output1 is connected to 4 LEDS that flash in sequence: 1, 2, 3, 4, 3, 2 indefinitely.

I'm getting a ton of feedback from the speaker as I go through the programming steps, and it's not playing any sounds.

  • I think I figured it out...not enough juice. Was hoping to fit all of this in a Pinewood Derby Car but that's not looking likely.

  • Brad Yes, that's definitely the reason!  Using coin cells with pretty much anything sound-related will cause "lack of juice" issues. :-(
