The device should have been taken care of by the initial setup of the
card.  And the two aplay results are contradictory.  The device
aliases are on top of the hardware plug.  So alsa is recognizing the
hardware before it creates the device aliases, then not recognizing
the hardware.  You can try aplay -D hw:0,0 as a long shot, but
it sounds to me like there is something very wrong.  I'm not an
expert in this by any stretch of the imagination; at this point I
would ask on the alsa-devel list at http://www.alsa-project.org.
Technically, you should ask on the alsa-user list, but that seems to
have low traffic and sound is so complicated the devel list is better.

Good luck.
