this is the routing of IEC958 left channel.  choose "PCM Out" here.

no volume. it's only the switch.
if you use "iec958" or "spdif" pcm device, it's turned on
automatically.

ditto.

choose the right one for analog capture source.

are they obvious?

they are the routing for analog outputs.
choose "PCM Out".  or, it's routed from the selected input.

this is changed automatically if "rate locking" and "rate reset" are
set up correctly.

they are read-only.

turn this off.

turn this on.


as said, for digital outs, use "iec958" device.  but you might need to
wrap "plug" layer to convert the formats, etc. to play back non-24bit
samples.

	% aplay -D plug:iec958 foo.wav
