Well, adding the exclamation mark

!defaults.pcm.card "CMI8768"

does not work either. It may look trivial, but changing the default card
 while preserving the fine-tuned device definitions the for each card in
/usr/share/alsa/pcm/* and /usr/share/alsa/cards/* has been an
unattainable peak for me so far. Neither have I been able to google it
anywhere. IMO there must be a simple way to do this key change.

Thanks a lot for suggestion and hints.

Pavel.
