I've never done this and don't have that kind of device, so I cannot
give you a definitive answer.
Anyway, I used to have a Hi-Fi DAC connected via S/PDIF fibre optics
cable. I could use this with the MPlayer option:
You can look at the documentation for "passthrough":
You can get a list of audio outputs supported by you MPlayer executable
mplayer -ao help

Yes, that is the MPlayer default behaviour, you need to explicitly stop
MPlayer from decoding and tell it to send the digital data to the device
if you want to override this default.
