These builds were based on 6.1.2. None of them worked. Also, even though I continued to boot with snd_usb_audio.dyndbg=+p, none of the kernel logs showed the debug messages that the other versions did. I'm baffled why this is. I did notice that the order that the detected sound devices appeared in alsa was varying. That's probably not relevant though.
