No sound input/output on Raspbian Bullseye #752

I'm currently attempting to transition my Voice Kit v2 to Raspbian Bullseye following its recent release. After installing all dependencies as specified in HACKING.md, as well as the proper audio drivers (#751), I still get no audio output or input from the Voice Bonnet.

Recording a file with arecord gives me a WAV file containing all zeros (after the magic bytes and header), and playing a known-good WAV file doesn't actually play anything. However, neither operation yields any sort of error, and aplay -l shows the sound card as expected. Also, flashing the official AIY image to my SD card causes sound to work immediately, so it's not a hardware/wiring issue.

Is there any existing guidance on this? Or, does the AIY team plan to release an official image based on Bullseye soon?

I upgraded to bullseye as well and for me aplay -l can't see any soundcards at all
