kernel version matches the user space library and utils version.

We tried with an empty alsa.conf but then the message:
ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default aplay: main:564: audio open error: No such file or directory
appears. However the card shows up /proc/asound/cards and alsamixer is able to access it.
Any ideas?
Try a newer version of alsa-lib. Possibly fixed, or give you a better error message. At least, this bad "assert" should be gone now.
isn't it an obligation to keep version of user space and kernel in sync?
alsa-lib keeps the backward compatibility. A newer alsa-lib works with an older kernel. If not, it's a bug :)
