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.
