3W Speaker Bonnet - I2S mmap

Post by carriedo01 »

Recently get a brand new Adafruit 3W speaker bonnet. I unsuccessfully try to install it in my Raspberry Pi 4 using latest Raspian OS bullseye 64 Bits and Python 3.9.2
The speaker bonnet was installed as HAT.
Since I have other Adafruit HAT boards installed in my built (DC motor HAT, Servo Motor HAT) I did make sure the 3 pins required (GPIO18, GPIO19 and GPIO21) for the speaker bonnet were free to be used.
I followed all instructions as per product webpage. First I used the automatic installation process, didn't work. Then I followed the step by step manual process and checked that all required components were installed correctly as per product webpage, didn't work either.

Problem: when executing the test files (I tested speaker-test -c2, WAV and MP3 files) there is no sound.

Then I run 'alsamixer' and selected 'snd_rpi_hifiberry_dac' and check the volume was at full level 100 then I tested again the 3 audio test files, didn't work.

I noticed when booting the Raspberry Pi 4 I get the following message: 'failed to load overlay I2S-mmap'

I realized the 3W speaker bonnet is a few years old project but since there is no warning in the product webpage about potential issues with newer Raspbian OS and the project stills active I just assumed could be installed without major issues. I could not find also any specific requirements in terms of Raspbian OS version for this project.

Help is need it.

Thank you.

Buster should work if you can rolling back to a legacy install. That or kernel pinning. The issue appears to have started being reported around kernel v5.15.84 release in January.
