If the card is present in /proc/asound/cards, alsa detected it just
fine, and you have to look at the Adroid sound system in order to find
out why it's not used. Unfortunately, Android decided not to use any of
the ALSA userspace code but reinvented the wheel, for which simple tools
like aplay are unavailable.
I guess you have to ask about that on a Android specific mailing list.
