get list of alsa soundcards: cat /proc/asound/cards
restart alsa: pulseaudio -k && sudo alsa force-reload
get a list of soundcards: aplay -l
blacklist a soundcard:
- get the driver name: cat /proc/asound/modules
- inside /etc/modprobe.d create a file with extension .conf with the line blacklist then the driver name
  - example: blacklist snd_hda_intel
you can change the order of sound cards in /etc/modprobe.d/alsa-base (as of ubuntu 22.04)
- this did not change the order of a USB sound card vs. built-in sound
