Audio Amp SHIM (3W Mono Amp) has anyone got this working on a Pi Zero W?

I got the line out version and I’ve been down the same road as you. Or the same dead end street. Have a look at this discussion and maybe you’ll get some clues if you’ve got the courage.

I’m trying to let it go. I’ve wasted too much time on this.

Now we know why it’s called “Pirate” audio. Good luck to you.
