Re: HDMI & USB sound card can't regular

Welcome to the boards

The index order is random when multiple cards are there, either use string values in the asound.conf (e.g.

defaults.pcm.!card "HDMI"

(this needs to be the identifier in square brackets in aplay -l) or fix the index order with modprobe config e.g. /etc/modprobe.d/alsa-base.conf

options snd-hda-intel index=-1
options snd-usb-audio index=-2

If that didn't work post the output of

aplay -lL

in code tags

Also note that if you're actually using pulseaudio/wireplumber you shouldn't need an asound.conf.
