Strange but doable if (1) you have a TV that will output S/PDIF from an HDMI source and (2) you are content to changing your AVR's HDMI setting all the time since, afaik, most AVRs can process HDMI audio (for their speaker outputs) or pass the audio out with the HDMI (for the TV), but not both at the same time.
