Is this a bug of "aplay" or au88x0 driver ?

^^^^^^^^^
It's already wrong. Instead of hw:0,3, plug layer is used.
Do you have any definition in ~/.asoundrc or /etc/asound.state?
Is /usr/share/alsa/alsa.conf is properly updated from the latest
alsa-lib, too?

Which definition in /etc/asound.state ?
alsa.conf and AU8830.conf from alsa-lib-1.0.8
