In moode 8 series (Bullseye), ALSA device/card assignments were fixed but in moode 9 series (Bookworm) ALSA uses dynamic device/card assignments i.e. during startup ALSA may assign a given audio device a card number different from what was assigned previously.
Why not just leave your DAC on?
You probably can't repro the issue since moode defaults to the first device ('0'), and in your case, it looks like the DAC is assigned to '0'. Question - do you have HDMI devices listed?
In a shell, alsamixer lists the sound cards as "default : 0 vc4-hdmi-0" and "default : 1 vc4-hdmi-1".
The fixed vs dynamic assignments almost certainly explains the new behaviour. I think if there's a way to stop the HDMI port being detected as an audio device, then that should work.
Do you how much power costs these days?
Yeah - no biggie as a workaround, but equally, not clean or efficient !
TrueNAS scale -> Pi 4 -> SMSL C200 DAC -> Naim NAIT 2 amp -> Theophany M4 floor standers -> ears
