Hi!
I have ordered an adafruit speaker bonnet to be used with my Raspberry Pi 4B.
The 4B has the problem, that there are 4 pins in the way, so it doesn't perfectly fit on top of my 20 pins.
So I did some wiring and hooked everything up like in the documentary. My power supply that came with the Pi delivers 5.1V and 3.0A, enough for the 3W 4 Ohm Speakers I ordered together with the Bonnet.

Speakers:

On Boot I get a short Pop (like most do from what I've read) - shortly followed by very loud static noise until the system is fully booted up. When I try a speaker test, it works, but the static noise starts as soon as the audio files from the speaker test play and the noise stays for like 5s after the final sample has been played - then it's back to silent again.
I couldn't find a way to change volume as well, so I thought this was the Software Volume Control-Issue mentioned in the documentation.
I'm using the latest Raspbian (Bullseye) - Is this still the mentioned issue? There has been no update since 2018 on this, at least I couldn't find any. Is there a solution for this? Installing a different OS is not an option for me, as most of the things running on my pi only work on the latest build.
Thanks in advance!
Edit:
I can play sound and I can also change the volume of it via the in-built OS-options. The only thing that is not changing is the static noise. It's VERY loud. Even when I go 0% with the output the static doesn't change. Any ideas?
Edit2:
On boot I get a message in the top right corner saying "failed to load overlay 'i2s-mmap'" as well. Could also be a bullseye-specific thing maybe?

Re: Adafruit Speaker Bonnet problems
Flashed a fresh install of Buster on another SD-Card, same result. Speakers are working (I can hear the samples) but the noise is also very present. Same thing here: As soon as something plays, static noise goes hard - When there's no more samples to play, after 4-5 seconds it goes back to silent.
I'm starting to suspect that this is a faulty PCB and not a software issue. :/
PS: On Buster I didn't get the "failed to load overlay 'i2s-mmap'"-Message. So that probably is a Bullseye-only-thing

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.
