Sound is not working on RPi != 5

Raspberry Pi Model

Raspberry Pi 4 B

Describe The Bug

Download and flash Homebridge image with RPi Imager.

Setup Codec Zero sound card by following the official documentation: https://www.raspberrypi.com/documentation/accessories/audio.html#raspberry-pi-codec-zero

Try to record sound: arecord -f cd test.wav

Recording is empty.

I have tested this on PRi4, RPi Zero WH and RPi Zero 2 W, same results - empty recording.

Do the same thing on RPi 5, everything works as expected.

Use RPi OS Lite or any other image on any RPi version, again everything works.

Logs

Error that arecord sometimes shows, but not always:
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

You could install RPI OS lite then install the homebridge apt package. That is what is done within the homebridge raspbian package.

That’s fine for me, but I am developing a HB plugin for hooking an analog intercom to HB and I don’t think that everyone would be willing to do this.

Anyhow, there is an issue that should be fixed…

As fixing this requires the HAT you are using, could you look into what is missing from the Homebridge Image, and we can add it.

The build is here, which is pretty straight forward - https://github.com/homebridge/homebridge-raspbian-image/blob/latest/.github/workflows/create_raspbian_pi-gen.yml
