I am working on a sound image based on raspiOS lite. I noticed with the 32 bit Bookworm Lite image that no sound is passed over the i2s interface. I use in the config.txt and use MPD to play audio. This only happens on the Zero2W and only with the 32 bit image. This same 32 bit (armhf - use on all pis) image with the same settings running on a Zero(1.1), 3b+, 4b works fine and I get audio over i2s. It is only on the Zero2W that I get no audio.
If I put an identically configured 64 bit image in the Zero2W, it passes audio over i2s and works fine.
These are the modules running on the zero2w regardless of the image (32 bit versus 64 bit)
Hardware model:Raspberry Pi Zero 2 W Rev 1.0
Anyone know what might be going on?
