What does this mean by "enable" - I'm guessing it's powering blocks within the CODEC rather than connecting any audio paths?
The TRM calls these as Audio/Voice digital filters. In effect, they enable the shifting out bits from the Capture path to the bus and shifting in bits on the Playback side.
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.
But as I said, this is not so nice thing to do, so it need to be revisited.
It needs digital routing. In the interim another option would be to provide switches to user space, possibly?
