I received my PiSound today.
I’ve mounted it on a working Pi 3 with a fresh install of Raspbian. But it won’t boot up. When I power it up I see the multicoloured square on the screen, then blackness. After 3 seconds it repeats.
I remove the PiSound and the Pi works fine. Reattach it and it won’t boot.
The Pi by the way is a 3B v1.2.
Is my PiSound defective?
