I  have created a /etc/modprobe.d/sound.conf now with:
alias snd-card-0 ca0106
options ca0106 index=0


Interesting is that a normal user can't find a sound card:
(That's different to the PC with the onboard sound with CM6501)

user at PC:~$ aplay -l

It's the same trying to play a soundfile:

Here it only plays noise, also with other soundfiles!

Soundcard 1 must be the deactivated onboard sound of the mainboard.
