Hello smart saber people! I am new to lightsaber construction so I am curious if someone could help with something.

I bought a nano biscotte V4.1 sound board pre soldered from The Custom Saber Company and after I wired it up to test it there was no sound. I made sure to format the micro SD card before loading the sounds and I also made sure the power was off before manipulating the card. The LEDs function beautifully and I was able to adjust the configurations for those so I am thinking the SD card and it’s reader are fine. I checked the board with a voltmeter and it looks like power is not getting to the speakers. Any ideas?

Someone from another group already suggested my amp is broken. If that’s true does anyone know how to repair or replace something like that?
