Hello Eric,

You should run the latest ALSA from the git tree because I added a codec
specific SPDIF output control control for that chipset.

 417 static const char *stac927x_spdif_labels[5] = {
 418     "Digital Playback", "ADAT", "Analog Mux 1",
 419     "Analog Mux 2", "Analog Mux 3"
 420 };

I haven't tested ADAT output though but I have no reason to
think it wouldn't work.
