In all likelihood, the devices are randomly switching order on boot.
Unless specified, if there is more than one device, they can alternate
at startup. Alsa can get confused between modem/soundcards and
soundcards.
So run either aplay -lLv or cat /proc/asound/cards to look at the
devices that alsa knows about.
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-1 snd-usb-audio
options snd-usb-audio index=1
to /etc/modprobe.d/sound or /etc/modprobe.conf on your system to
specify which card becomes which device, changing the snd-???????
entries to reflect your actual devices from the commands
above.
