Its lol. 16 bit mode should not be used as it adds noise (dither) for smoothing (quantization feature associated with to reproduce a material of lower bit depth on a higher bit depth of the sound card). Try it yourself to listen to something trite in the 16-bit sound card mode and in 24-bit (but this does not apply to the source of the sound, music or other recordings there ... ). In moments of pause and transition from silence to loud sounds, there will be such background noise similar to telephone. Specifically now, of course, I already have no opportunity to retest this all again. But I think the other day I will repeat the experiments with another laptop. In general, for the purity of the experiment, I would put windows 7 on my PC, where xonar dx is installed, but it’s hard to install this rudimentary on current platforms (kaby lake). Of course, deviations are possible that the drivers have some kind of fixes for the seven and other magic, but in my case the drivers were the same everywhere with the same conditions.
