You can enforce that a sound card becomes alsa hw:0 and nothing else is
required, since the sound servers use alsa.

Write a /etc/modprobe.d/alsa-base.conf with

options snd slots=driver_name

for example

$ cat /etc/modprobe.d/alsa-base.conf 
# ALSA module ordering
options snd slots=snd_hdspm,snd_ice1712,snd_ice1712

I just noticed, that on my machine the do-release-upgrade must have
removed some very important configs,
seemingly /etc/modprobe.d/alsa-base.conf, too.
