At the position after the CODEC we measure 10µV if the TPA6404 is disconnected.
When we connect the TPA6404 the noise increses to 35µV at the same position (after the CODEC, on the inputs of the TPA6404).
As a result the noise measured at the power stage output is 1mV.
Are there any experience with high noise on the TPA6404 outputs?
