Hi macpac,

The power supply is probably too weak. We recommend using a 5V 2.5A PS for the Raspberry Pi 3 with a sound card HAT in general. For the MiniAmp it might even be recommendable to use 3A.

Also, make sure the speakers you use are only around 3W each as that is the maximum capacity of the miniamp. What wattage do your speakers have?
