PCM5102A in 1.8V mode. Separate 0.1 and 10uF caps for DVDD an LDOO?
The linked forum talks only about XSMT. How to connect LDOO when your digital signals use 1.8 V is only mentioned there, but explained in the datasheet itself:


  When setting I/O voltage to be 1.8 V, both DVDD and LDOO must be provided with an external 1.8-V supply.


You do not need separate capacitors, because


with both pins connected together, all capacitors are in parallel (and the pins are near enough so that the trace inductance should not matter); and
the capacitor(s) on LDOO would be needed to decouple the internal LDO, but when you are feeding external power into this pin, the internal LDO is disabled, so you do not need bypassing anyway.
