I really have no clue. I had it working, developed an app using picovoice porpupine/pvrecorder, vosk, google TTS... I made a new SD card, flashed a new image of bookworm 64 bit, and I could not reinstall the driver. Problem with dkms, linux-headers, etc... Finally after many tries and reboots it's ok, listen in aplay -l and arecorder -l, but pvrecorder 1.1.1. doesn't see it. Has anyone had any luck ? Even with bullseye I see similar problems.
