Clock signals aren't time code signals that by software can be
translated into another code. Converting a spdif clock signal to word
clock has to be done electronically. Assumed your device should be able
to convert the signal it gets from an spdif master, it's questionable
if such a daisy chain would be a sane solution. I don't know if any
device makes such conversions. AFAIK there are master clock devices
that provide spdif and word clock outputs. Keep in mind, only one device
could be the master, all other devices are slaves. A daisy chain
without converting the signal already should be avoided, that's why
expensive clock devices exist. The problem with a clock signal is
electronically accuracy, it's not translating a software protocol.
