Yan,

My guess:

defaults.pcm.card has a type of integer in the alsa.conf.  You are
trying to override it with a string type.

If you want to use a pcm of type hw (or plug on hw), consider using the
shell to evaluate an appropriate value (based on $DISPLAY) for ALSA_CARD
or ALSA_PCM_CARD in the user's .xinitrc.  See lines 132-231 in alsa.conf
(v1.0.15).
