What does this mean by "enable" - I'm guessing it's powering blocks
within the CODEC rather than connecting any audio paths?

What are the problems other than loopback (which really needs digital
routing to work properly, though I've never seen much demand for it
outside of testing)?  Powering everything is probably fine, I'm just
wondering if this is due to the hardware or the core.
