Default by default is hw:0 and you can ensure that hw:0 is always reserved for the same device. $ cat /etc/modprobe.d/alsa-base.conf # ALSA module ordering options snd slots=snd_hdspm,snd_ice1712,snd_ice1712 You could add snd_usb_audio as first device, so hw:0 would be reserved for an USB device, even if it's not connected. For me hw:0 is reserved for a RME card and hw:1 and hw:2 are reserved for Envy24 cards, even if I e.g. remove the Envy24 driver, an additional connected device, e.g. an USB device, becomes hw:3 and not hw:1.
