From what I'm seeing from the schematic, you shouldn't need to do anything else. Did you check the signal levels on the DAC's pins itself? Both the clock and the Bt* pins? Are the voltage levels correct? (i.e. 0-3.3V)

Where are you measuring the DAC output? You should do it before the transformer as it would cut out the DC part of your signal.
