Hi guys,

I have a Pico Crumble and a 1.5w speaker, both from CSS. I wired up the Crumble, the Speaker, and the activation switch just to do a test. What I found was really strange. At first it was beeping constantly. Almost like it was "hiccuping". I don't trust my power supply, so I switched to an 18650 that I knew would provide reliable current/voltage. My results were still very strange. Upon activation, it would make the turning on sound, but then it would constantly be clashing. Even though every component was sitting quietly on an ESD map. To that note, I've done all my soldering at my bench on an ESD mat, the board shouldn't have been damaged.

First time working with a sound board. Have a made a dumb mistake? Is my pico crumble bad? I only have a week to finish this guy so I'm a little stressed. Any help would really be appreciated.
