I forgot I actually do have one machine that sets up two devices:

# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##  ALSA portion
alias snd-card-0 snd-intel8x0
options snd-intel8x0 index=0

alias snd-card-1 snd-usb-audio
options snd-usb-audio index=1

##  OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1

# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
##  OSS/Free portion - card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
options snd cards_limit=2
