the hardware has no mixer.

shouldn't be a problem.

there are a couple of ways. alsactl is probably the most obvious:
% alsactl -f foo store
... edit "foo" ...
% alsactl -f foo restore
in the file "foo" generated by the first step, you will find lots of
stuff, including this:
control.5 {
comment.access 'read write'
comment.type ENUMERATED
comment.item.0 ADAT1
comment.item.1 Coaxial
comment.item.2 Internal
iface PCM
name 'IEC958 Input Connector'
value Coaxial
}
control.6 {
comment.access 'read write'
comment.type BOOLEAN
iface PCM
name 'IEC958 Output also on ADAT1'
value false
}
You will want yours to look like this:
control.5 {
comment.access 'read write'
comment.type ENUMERATED
comment.item.0 ADAT1
comment.item.1 Coaxial
comment.item.2 Internal
iface PCM
name 'IEC958 Input Connector'
value ADAT1
}
control.6 {
comment.access 'read write'
comment.type BOOLEAN
iface PCM
name 'IEC958 Output also on ADAT1'
value true
}
which will then do S/PDIF I/O over the ADAT1 connector.
using amixer is quicker but terser and you have to know/understand a
bit more to use it confidently.

no, they are for co-axial S/PDIF output. there is no analog I/O of any
kind on this card.
