Couple things.
1. The HDMI ports can't be disabled or turned off in Bookworm.
2. I was testing on a Pi 3B+ which has 1 HDMI port. ALSA card 0 is Rev DAC and card 1 is Pi HDMI 1.
3. Re cost of power. The US where I live has a high cost of living relative to other countries and for sure things get turned off when not being used.
I'm not sure your issue is because of ALSA card reassignment. I'll run some tests later today on a Pi 4 and see what happens.
