It's pretty uncommon in the embedded world too, you'll often see the
input and outputs all being mutually exclusive (or only able to take the
same signal) but it's very unusual that the output would force a
particular input.

It is common for systems to do this from a use case management point of
view (always using the headset if it's present for example) but that's
not normally a hardware restriction.
