Only a knocking sound when starting

[Oburi1985]

Hi, I have a problem with the soundboard. I got only a fast "knocking" sound when I start the pack. I already checked all the wiring, but nothing helped. Anyone had the same issue before? Thanks guys!

The sound board is one of the things that can be tested outside of the full software using a tutorial from adafruit. I always recommend people test the audio board following the instructions as it's really straight forward and you can interactively mess with the board. Here is the documentation

When debugging wiring, having a simpler setup to work with is a huge help.
