Since I don't have the Layla20 anymore I don't think I can be very 
helpful here. You probably already know about aplay -l and aplay -D 
hw:c where c would be your Layla number from aplay -l.

Have you set up your modules.conf? I had 

# snd
alias char-major-116 snd
alias char-major-14 soundcore

# layla20
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
alias snd-card-0 snd-layla20
alias sound-slot-0 snd-layla20

in there (Call depmod -A if you change it). Depending on your setup the 
first 0s could of course be 1s or whatever. Try alsaconf anyway.
Contact Giuliano Pochini <pochini at shiny.it>, he knows the wire and he's 
very helpful.
