I rebuilt this configuration as stated in the guide by Riccardo Raponi. The Raspberry Pi Zero W and the MiniAmp seem to run fine but there is no sound coming out of the speaker. As I understood, the speaker needs no extra power but only needs to be attached to the MiniAmp? What could be the problem?

macpac It seems the MiniAmp only offers a 3W output but the speaker needs 5W. I wonder how Riccardo Raponi has solved this issue? :-(

HiFiBerry team Hi,
the speaker does not "need" 5W. A power rating on a speaker only tell what the maximum power is that a speaker can accept without being damaged.
What is the output of "aplay -l"?

HiFiBerry team This looks good. Most likely there is a hardware problem in your setup. In most cases, the solder connections on the GPIO of the Raspberry Pi Zero are not good. Please check the solder connections on the Zero GPIO header.

macpac I will check this although the guide said that no soldering would be required...

HiFiBerry team Hi,
no soldering on the board, but you need to solder a GPIO header to the Raspberry Pi, if you're using the Zero-W as it does not come with a header mounted.

macpac Hi Daniel,
as I'm no soldering hero, I bought a Raspberry Pi Zero WH with the header already being attached. Now everything works fine. Thanks for the support!
Best regards,
