Hrm, so this is a routing thing then - from your description I'm a bit
surprised that this can be turned on unconditionally since it sounds
like it'll give you a sidetone all the time which might not be what
people want.

It needs digital routing. In the interim another option would be to
provide switches to user space, possibly?
