Built the Jay-D with my son (he did most of the soldering). Tested it along the way and it was fine. When we got the whole thing together we are having what I can only describe as intermittent cut-outs in the sound - basically the tracks play, then they “skip” or really “drop out” (there’s a video below where you can hear it). We have tried to isolate the issue to one of the potentiometers or something but it seems fine, they all test without issue.
It doesn’t appear to be a power issue as the display and LEDs continue to work. We tried several different power supplies just to check (all 2A). Tried using headphones in case it was a speaker issue - the same issue was evident. I suspect I need to pull it apart to check all the soldering but before I do that I would see if anyone had any other ideas.
