Please do (tseted on my PB):

# /etc/init.d/alsa force-unload
as long till
# lsmod | grep snd
is empty.

Then
# modprobe -v snd_aoa_i2sbus
or just reboot.

No more /etc/init.d/alsa reload needed. Please rely on udev.

Here's what I got:

aoa-tas driver isn't recognizing it because my card is too old?
