I guess the registers above were not dumped during spdif playback.
Right?

The syntax of aplay is different between ALSA 0.5.x and 0.9.0.
For 0.5.x, use -d option to specify the device number, i.e.
% aplay -d2 test.wav

Please turn off "DAC to Out" for the time being.
It's a mixture of analog streams and looks not suitable for the recent
chips.
At first please try to turn only "SPDIF Output Switch" on and other
SPDIF-related switches off. If still not work, please try to turn on
both "SPDIF Output Switch" and "SPDIF Out To DAC" (not "DAC to
Out").

Basically there has no big changes in the 0.5.x serie since SuSE 7.3
was released. So you can keep it as long as it works :)
ciao,
Takashi
