Sound like you might just need to index the alsa modules so they load in a specific order. Automations scripts might be working in strange ways. udev / discover / ... plus mixer restoration. It could just depend on which card get hits first in terms of restoring mixer settings, and/or loading modules.
Perhaps something like this in your configuration would help. Modify to use your specific cards. You don't have to disable the card in the bios. At least in a perfect world.
/etc/modprobe.d/(whatever yours is called, alsa, alsa-base, alsa_custom)
