The approach you've been taking sounds reasonable; at this point I'd be
looking at trying to confirm that the controller is doing what's been
asked of it.  Checking that the CODEC power rails are all within spec
and looking at other bits in the same register may also be useful.

Is the system otherwise idle when the problem occurs?
