I don't know how it works for HDMI, but if it does update that list
based on the receiver, that would be ideal for us, since we should be
able to probe that while routing.

For S/PDIF, we don't have that option so I guess we'll need to add some
additional checkboxes to GUIs so users can select what formats their
receiver supports.
