Hm. That would include playing with those settings:

Master switch, as you can see, digital output (Playback) is enabled,
digital input (Capture) is disabled:

I think those two relate to input/capture only:

I'm not sure about the next two items, maybe playing with them is a
good idea, too:

If alsamixer doesn't provide the according settings, you might want to
use "amixer sset <control> <value>", see "man amixer" for synopsis and
examples.

I really guess it's due to one of the IEC958 (i.e. digital in/out)
settings.
