Accessing SPDIF device won't work unless you set up some controls
properly beforehand.  Usually SPDIF devices are accessed via "spdif"
(or "iec958") PCM, which will do this job automatically.

In most cases, secondary (or later) devices are _not_ supposed to work
by the direct access.  Many of them are designed for special use.

I'd recommend to list up only the card names, and try to use either
"default:X" or "plughw:X" (the former is preferred, but not available
in the older version).
