Or more correctly, most of the digital filtering is bypassed. There is still a gentle wideband filter applied. And all of the audio digital filters (or DAC in this case since the DF is in the same package as the D/A convertor) I'm aware of oversample the input regardless of the sample rate, that is what the maximum sample rate specification is for. One could control externally whether the input bypasses the digital filter at higher rates, and that is done by some, but it isn't commonplace when using separate digital filter and D/A convertor parts because it requires extra logic to get the signals in the right format if you bypass the DF. On the Wolfson, it is via an extra data input since the signals need to be in the correct format with separate left and right data.
