I think the binding should be changed to replace the word "dummy" with
"generic" and perhaps some verbiage about not requiring software
configuration.  I think given the unidirectional nature of S/PDIF it's
reasonable to represent a jack like this - the hardware can't generally
tell if there's anything at the other end of the link anyway, for all
pratical purposes the transmit end just has to blindly send.
