Hello guys! I got another problem now: no sounds from the adafruit amplifier.

I drew a diagram to show how I wired things up, if needed I can post the prototype that I'm working on. Its quite messy though.

Here's the diagram:


I've confirmed that isn't because of the speaker, and neither the audio input. Also the power are functioning correctly as well.
I'm really confused now...

The Audio GnD goes to the Amp GnD. The A- is for alternative audio in the event you get different sounds on different channels.

This is probably silly, but you have tried the volume trimpot on the amplifier?

Thanks! Thats why!
But now I got audio with really low volume and poor quality. Also with buzzing sounds...
No problem when I'm using a 3.5mm jack and without the amp..
