Better than no sound :) At least something is getting through ALSA and
ASoC to your codec.
You may need to adjust the RCMR, RFRM, TCMR, TFRM register settings in
sound/soc/at91/at91-ssc.c to send the data in the mode that your codec
expects. I have only tested I2S and DSP_A modes with S16_LE data. It's
fairly easy to add new modes.

I don't see anything wrong with this alsa.conf, but I'm no expert. It
is virtually the same as the one I am using, but I am using ALSA 1.0.13.
Here is the bare-bones config file that I was using before I added a
second sound device:
pcm.!default {
type hw
card 0
}
pcm.hw {
type hw
card 0
device 0
subdevice 0
}
ctl.!default {
type hw
card 0
}
ctl.hw {
type hw
card 0
}
