The target is, that hw:0 is the RME card, named by it's original name hw:1 is Envy card 1 , named by it's original name hw:2 is Envy card 2 , named by a customized name any USB device should become hw:>=3 and get it's original name, even if snd_ice1712 isn't loaded. Excepted of the customized name, this is provided by /etc/modprobe.d/alsa-base.conf. The below udev rule doesn't work [1].
